Islamic Civilization and Science: What History Actually Records
·28 min read·6218 words
Islam does not merely permit the pursuit of knowledge — it commands it. The Quran repeatedly calls humanity to observe, reason, and reflect on the created world as a path to recognizing its Creator. This post traces the historical record of Islamic civilization’s contributions to science, medicine, astronomy, mathematics, and education — drawing on Western historians, secular scholars, and the admissions of critics themselves — while documenting the contrasting posture of medieval Christian Europe toward knowledge and cleanliness.
Thinking and Contemplating Is the Path to Knowledge
Al-Baqarah 2:164 Indeed, in the creation of the heavens and the earth, and the alternation of night and day, and the great ships that sail through the sea with that which benefits people, and what God has sent down from the sky of water, by which He has revived the earth after its lifelessness, and has dispersed therein every kind of moving creature, and in the directing of the winds and the clouds controlled between the sky and the earth, are signs for a people who reason.
The Quran frames the entire natural order — oceans, weather, biology, celestial mechanics — as a field of inquiry for those who reflect. This theological foundation for empirical curiosity distinguished Islamic civilization from the outset.

It argues that Islam established a lasting moral and social framework based on justice, which allowed civilization to flourish.
Gustave Le Bon — further passage on Islamic civilization's foundations
Islamic Civilization Is the Religion of Knowledge
Sahih Muslim — On Knowledge That Endures The Prophet ﷺ said: “When the son of Adam dies, his deeds come to an end except for three: knowledge that is beneficial, ongoing charity, or a righteous child who prays for him.”
Grade: Sahih · Muslim
Islam institutionalized the pursuit of knowledge as an act of worship with eternal reward. The historical record reflects this:
The ceiling of the Library of Congress is decorated with the word “Islam” as one of the twelve sources of knowledge and civilization recognized by that institution.
NASA named a mountain range on the surface of Pluto after the Muslim geographer and cartographer Al-Sharif Al-Idrisi.

Islamic Civilization Is Built on Causality
On Causality and Trust in God The Prophet ﷺ said: “Tie your camel, then put your trust in God.” He also said: “You are more knowledgeable about your worldly affairs.”
Grade: Hasan · Ibn Hibban
Islam — not atheism — is the philosophical foundation that makes science possible. The doctrine that the universe operates according to fixed, discoverable laws flows directly from the Islamic understanding of God as the Self-Sustaining Creator who governs creation consistently. Without that theological premise, there is no rational basis for expecting that experiments will be repeatable, or that natural laws discovered today will hold tomorrow. Atheism, which claims existence is coincidental and random, provides no such guarantee.
Ibn al-Qayyim — Shifa al-'Alil fi Masa'il al-Qada' wa al-Qadar, highlighted passage on causality
Ibn al-Qayyim — Shifāʾ al-ʿAlīl fī Masāʾil al-Qaḍāʾ wa al-Qadar “We do not know of any book more affirming causes than the Qurʾan. Rather, if Allah is the creator of the cause and the result, then He is the One who made this a cause for that. Causes and effects occur according to His will, power, and wisdom. If He wills, Allah can nullify the effect of a thing, just as He nullified the burning effect of fire for His close friend Ibrahim.”
Ibn al-Qayyim — Shifa al-'Alil, continuation of the passage on divine causality
The passage above continues the discussion of how divine will operates through — not against — natural causes.
Ibn al-Qayyim — further pages establishing the Islamic framework of causality
The Islamic scholarly tradition articulated a precise framework governing the relationship between religious certainty and scientific inquiry. Four principles govern this:
Summary diagram — the four principles governing religion and science in the Islamic tradition
🔷 The supernatural cause of a phenomenon does not contradict the existence of a material cause for it.
🔷 It is impossible for what is religiously certain to conflict with what is scientifically certain.
🔷 If what is conjectural in religion conflicts with what is conjectural in science, the one who has stronger evidence between them should present the alternative.
🔷 If what is conjectural in religion conflicts with what is definitive in science, then the scientific explanation is presented.
Ibn Taymiyyah — Majmu' al-Fatawa, highlighted passage on thunder and natural causation
Ibn Taymiyyah — Majmūʿ al-Fatāwā The highlighted text explains that thunder is caused by the compression and collision of clouds, while lightning comes from the fire generated by that collision. It states that these are natural causes created by Allah, while at the same time thunder, lightning, eclipses, earthquakes, and similar events are also signs through which Allah warns His servants. Mentioning the natural cause does not cancel the divine sign, and mentioning the divine sign does not cancel the natural cause.
Ibn Taymiyyah — Dar' Ta'arud al-'Aql wa al-Naql, passage on the impossibility of conflict between certain truths
Ibn Taymiyyah — Darʾ Taʿāruḍ al-ʿAql wa al-Naql The highlighted text states that if two definitive proofs appear to conflict, then one cannot truly negate the other, because real contradiction between two certain truths is impossible. If one proof is certain and the other is speculative, then the certain proof takes precedence, because speculation cannot override certainty.
Ibn Taymiyyah — Al-Radd 'ala al-Mantiqiyyin, passage on Muslims excelling in mathematics, medicine, and engineering
Ibn Taymiyyah — Al-Radd ʿalā al-Manṭiqiyyīn The highlighted text states that many later Muslim scholars occupied themselves with mathematics, calculation, medicine, and engineering, and praised these sciences because they are correct sciences in which error does not enter.
Ibn Taymiyyah — Al-Asbab fi al-Tafsir, on the coexistence of physical and unseen causes
Ibn Taymiyyah — Al-Asbāb fī al-Tafsīr The highlighted passage explains that some physical causes are linked to unseen causes. For example, the physical cause of thunder may be understood scientifically, while revelation also teaches that angels are connected to these events. Mentioning an unseen cause does not cancel the physical cause, and mentioning the physical cause does not cancel the unseen one.
Europe in the Middle Ages
Medieval Christian Europe stood in stark contrast to the Islamic world in its relationship to cleanliness, knowledge, and public health. The Prophet ﷺ established principles of hygiene centuries before European civilization began recovering them from Muslim sources.
On Public Cleanliness The Prophet ﷺ said: “Beware of the three curses: defecating in watering places, in the middle of the road, and in the shade.”
He also said: “Removing something harmful from the road is charity.”
He said: “Removing a stone, thorn, or bone from the road is considered charity for you.”
Grade: Sahih · Muslim (first hadith)
Will Durant — Qissat al-Hadara, highlighted passage on London's filth and poverty in the Middle Ages
Will Durant — Qiṣṣat al-Ḥaḍāra (The Story of Civilization) The highlighted text states that London remained poorly lit for centuries, with muddy streets, little drainage, and widespread poverty and crime. It notes that poor children often grew up neglected, half-starved, and vulnerable to theft and violence.
Will Durant — Qissat al-Hadara, passage on the disappearance of public baths in Christian Europe and their reintroduction from Muslim lands
Will Durant — Qiṣṣat al-Ḥaḍāra The highlighted passage explains that cleanliness was not common in medieval Europe. Public baths disappeared after the early Christian period because they were associated with immorality, while steam baths from Muslim lands were later introduced into Europe. Church authorities often opposed public baths for moral reasons.
Muhammad Abdullah Inan — Madinat al-Muslimin fi Isbaniya, passage on forced assimilation policies after the fall of Muslim Spain
Muhammad Abdullah Inan — Madīnat al-Muslimīn fī Isbāniyā The highlighted text states that after the fall of Muslim rule in Spain, Queen Isabella I of Castile issued decrees preventing Muslims from wearing their traditional clothing, speaking Arabic, or practicing their customs openly. It describes this as part of a broader policy of forced assimilation.
Stanley Lane-Poole — Qissat al-Arab fi Isbaniya, passage on the destruction of public baths after the return of Christian rule in Spain
Stanley Lane-Poole — Qiṣṣat al-ʿArab fī Isbāniyā The highlighted text states that public baths were widespread in Muslim Spain and were viewed as a necessary part of worship and cleanliness. It contrasts this with Christian Europe, where public bathing declined, and notes that after Christian rule returned in Spain, public baths were destroyed because they were seen as traces of Muslim influence.
The Impact of Christianity on Science
Christianity’s Rejection of Cleanliness and Knowledge
Purity in Islam The Prophet ﷺ said: “Purity is half of faith.”
Grade: Sahih · Muslim
Al-Baqarah 2:269 And whoever has been given wisdom has certainly been given much good.
The Quran affirms wisdom and knowledge as great gifts from God. Biblical texts, by contrast, were used by medieval Christian authorities to discourage inquiry:
1 Corinthians 1:19 (KJV) “I will destroy the wisdom of the wise, and will bring to nothing the understanding of the prudent.”
Proverbs 3:5 (KJV) “Trust in the Lord with all your heart and do not lean on your own understanding.”
These verses were employed in medieval Christendom to subordinate reason to clerical authority — an orientation that produced measurable consequences for European civilization.
Yuhanna al-Sayyid al-Barmuni — Tarikh al-Ummah al-Qibtiyyah, passage on dirt and foul smells being associated with Christian piety
Yuhanna al-Sayyid al-Barmuni — Tārīkh al-Ummah al-Qibṭiyyah The highlighted text states that public bathing was considered shameful in parts of medieval Christian society.

Thomas Walker Arnold — Al-Da'wah ila al-Islam, passage on why Byzantine populations were attracted to Islam
Thomas Walker Arnold — Al-Daʿwah ilā al-Islām The highlighted text states that many people in the Byzantine world were attracted to Islam because it offered a simpler faith, a direct relationship with God, moral clarity, and freedom from complex priestly systems. It also says that oppressed groups often saw Islam as a source of justice and hope.
Sigrid Hunke — When the Sun of the Arabs Shone on the West, passage on dirt and foul smells becoming normalized in medieval Europe
Sigrid Hunke — When the Sun of the Arabs Shone on the West The highlighted passage explains that in parts of medieval Europe, many people bathed very rarely and often wore the same clothes for long periods. It says that dirt and foul smells became normalized, while Muslim influence later helped restore practices of bathing, cleanliness, and personal hygiene in Europe.
Epidemic
On Seeking Medical Treatment The Prophet ﷺ said: “Seek treatment, for God has not created a disease without also creating a cure for it.”
Grade: Sahih · Abu Dawud, Ibn Majah
Europe, drowning in waste and rejecting personal hygiene under the influence of the Church, faced catastrophic epidemics. The Church forbade treatment, teaching that illness was divine punishment, and regarded medicine as heresy. The Muslim world, by contrast, produced giants of medicine and surgery — Ibn al-Nafis, Ibn Zuhr, and al-Zahrawi — without parallel in contemporary Europe.
Heleen Meeserie — Sexual Taboos in Christian History, passage on the church discouraging medical treatment during plagues
Heleen Meeserie — Sexual Taboos in Christian History The highlighted text states that during major plagues in Europe, many church leaders taught that disease was divine punishment and discouraged scientific or medical approaches. It says that after the plague, church influence over medicine increased, leading to widespread use of practices such as bloodletting. The passage also claims that church teachings discouraged bathing and hygiene, contributing to poor sanitation and the spread of disease.

The source material continues, documenting the mortality rates of European plagues accelerated by the suppression of hygienic and medical knowledge.
Further documentation — plague, church authority, and the rejection of Muslim medical advancesAdditional source — comparative mortality and the Church's prohibition of treatment
Scientists Are Heretics in Christian Europe
Unlike Islam — which honored wisdom and elevated scholars — Christianity accused every scholar who challenged the myths of the Bible of heresy and sentenced many to death.
Al-Baqarah 2:269 And whoever has been given wisdom has certainly been given much good.
1 Corinthians 1:19 (KJV) “I will destroy the wisdom of the wise, and will bring to nothing the understanding of the prudent.”
Will Durant — History of Christianity in the Reformation Era, passage on scientific questions being treated as religious matters in medieval Europe
Will Durant — History of Christianity in the Reformation Era The highlighted text states that in medieval Europe, educated people often viewed knowledge through church doctrine. It says that questions about whether the Earth moved, whether the Sun moved around the Earth, or whether the Earth was spherical were treated as religious issues rather than scientific ones.
Michel Hanna — 30 Horrific Methods of Execution, passage on witchcraft accusations and mass executions of women in medieval Europe

Andrew Dickson White — Between Religion and Science The highlighted text describes the treatment of . It states that he was threatened with physical torture, forced to kneel and publicly recant his support for the idea that the Earth moves, and pressured to declare belief in the opposite view.
Christianity and the Degradation of Human Reason
Christianity, in its medieval institutional form, agreed with atheism’s materialist premise in one crucial respect: it treated the human mind as untrustworthy and unworthy of cultivation. The Biblical passages deployed by medieval church authorities to justify this included:
Job 11:12 (KJV) “For vain man would be wise, though man be born like a wild ass’s colt.”
Ecclesiastes 3:19 (KJV) “For man has no advantage over the beast.”
The consequence of this theological posture was a deliberate suppression of education across medieval Christian Europe.
Muhammad Abdullah Inan — Madinat al-Muslimin fi Isbaniya, contrasting education in Christian Europe and Muslim Spain
Muhammad Abdullah Inan — Madīnat al-Muslimīn fī Isbāniyā The highlighted passages state that education in medieval Christian Europe was limited, expensive, and often restricted to nobles and clergy, while literacy among ordinary people remained very low. In contrast, Muslim Spain is described as having widespread access to education, public libraries, book markets, and schools open to different social classes. Even ordinary people, women, craftsmen, and farmers could often read and write, and books were widely available. Many European students traveled to Muslim Spain to study science, medicine, philosophy, literature, and engineering, because Muslim cities offered advanced schools, libraries, and intellectual life that were not available elsewhere in Europe at the time.
Muhammad Abdullah Inan — continuation: European scholars traveling to Muslim Spain for education
The passage continues, documenting the flow of European scholars southward to Muslim Andalusia.
Muhammad Abdullah Inan — further passages on the intellectual gap between Christian Europe and Muslim Spain
The documentation above establishes that Muslim Spain was educationally and scientifically far ahead of Christian Europe throughout the medieval period.
Gustave Le Bon — The Civilization of the Arabs, passage on Arab civilization's superiority and its influence on medieval Europe
Gustave Le Bon — The Civilization of the Arabs The highlighted text states that the Arabs were among the greatest nations in history in terms of political organization, culture, and ethics. It says that medieval European nations learned many aspects of civilization from them, and that Europe’s later advancement was built upon foundations inherited from earlier Arab achievements. The passage also says that, compared to many earlier European societies, Arab civilization reached a higher level of refinement, knowledge, and moral development, and that medieval European universities often relied on Arab books, methods, and scholarship.
Muslims’ Rescue of the Greek Heritage
Muslims saved the ancient Greek heritage from Christian destruction. After Christianity became the religion of the Roman Empire, Europe rejected and abandoned the sciences of antiquity — destroying knowledge in both West and East, including the burning of the Library of Alexandria. Muslim scholars translated the surviving texts, preserving them when no one else would. Without this preservation effort, Europe would not have recovered its own intellectual heritage.
Gustave Le Bon — The Civilization of the Arabs, passage stating Europe's Renaissance would have been delayed by centuries without Arab civilization
Gustave Le Bon — The Civilization of the Arabs The highlighted text states that Europe owed much of its intellectual revival to the Arabs. It says that if Arab civilization had not preserved and developed the sciences of the ancient world, Europe’s Renaissance would have been delayed for centuries.
Andrew Miller — Mukhtasar Tarikh al-Kanisa, passage on Arabs reviving classical learning and becoming teachers of Europe
Andrew Miller — Mukhtaṣar Tārīkh al-Kanīsa The highlighted passages state that during Europe’s intellectual decline, Arabs revived classical learning, preserved Greek literature, and became teachers of philosophy, medicine, and science.

It says that Islamic civilization played a major role in preserving Greek heritage and transmitting it to Europe, which later made these works central to Western academic study.
Muslims’ Correction of Ancient Sciences and Invention of New Ones
Without Ibn Rushd and his commentaries, the West would not have known Aristotle. But Muslims were not satisfied with merely translating the ancient sciences — they corrected their errors. Ibn al-Haytham wrote Doubts About Ptolemy, and al-Razi wrote Doubts About Galen. Muslims invented new sciences entirely, some of which were later claimed by Western civilization. Arabic remained the international language of science for seven centuries.

Muḥammad ibn Mūsā al-Khwārizmī developed what are now called algorithms — named after him — which form the mathematical foundation of all modern computer programming. He is also the namesake of algebra (al-jabr), derived from the title of his foundational treatise.
Medicine
Taking precautions is one of the most important objectives of Islamic law. The Prophet ﷺ commanded seeking treatment; God does not create a disease without also creating its cure. Christian Europe, by contrast, forbade medical treatment on the theological grounds that illness is God’s punishment, and treated precautionary medicine as a contradiction of faith in God’s power. When Christian powers gained dominance, they burned the medical books of Muslims — just as they had burned those of the Greeks before them.

The Question of Atheism Among Islamic Scholars
Some critics attempt to claim that the great Muslim scholars were secret atheists or agnostics. This claim collapses under scrutiny. The Arabic term ilhad means “deviating from the origin,” not denying God. The scholars sometimes accused of religious irregularity were accused for specific doctrinal errors — not for denying God’s existence. None of the major scholars denied God. Some expressed heterodox philosophical positions; some later repented. Their own books are the evidence.

Hadith Science: Islam’s Revolution in Historical Methodology
ʿIlm al-Ḥadīth is the science that studies the transmitters of reports, hadiths, and narrations — criticizing, authenticating, and grading them — and establishes the criteria by which narratives are accepted or rejected. This discipline caused a revolution in the science of history. Even the weakest hadith in Muslim scholarship is more rigorously authenticated than the texts attributed to Aristotle, Plato, and the ancient philosophers — texts that were transmitted, cited, and attributed across centuries without any comparable verification apparatus.
Some critics attack hadith — especially al-Bukhārī — in a desperate attempt to undermine the Sunnah that explains the Quran, dismissing the chain of transmission (isnād) as unreliable. In doing so they destroy the basis of most human knowledge, since the overwhelming majority of what humanity knows was transmitted rather than directly witnessed.

Egyptology: Muslims as the First Decipherers
The ancient Egyptians enjoyed a rich civilization whose knowledge passed to the Greeks. When Christianity became the religion of the Roman Empire and rejected science and civilization, all sciences were neglected — and even the use of hieroglyphic letters was forbidden — leading to the loss of Egypt’s heritage. The first to attempt to decode hieroglyphic symbols were Muslim scholars, not European Egyptologists.

Hieroglyphics: Muslims Preceded Champollion
Today’s Christians attempt to claim the civilization of the ancient Egyptians as part of their heritage — even though the instrument of that civilization’s destruction was the Christian religion itself, which worked to destroy Egypt’s monuments, replaced Egyptian letters with the letters of the Greek conquerors, rejected the religion of the ancients, and embraced the language of the Bible. The Muslim scholars preceded Champollion in decoding hieroglyphics by nine centuries.

Ahmad Ibn Wahshiyya
Aḥmad ibn Wahshiyya authored the book Shawq al-Mustahām fī Maʿrifat Rumūz al-Aqlām — printed in London in 1806 — in which he decoded more than half of the hieroglyphic alphabet. This work dates to the tenth century: nine centuries before Champollion’s celebrated decipherment.
Islamic civilization was not incidental to the history of science — it was its engine. From the experimental method to algebra, from hospitals to universities, from hadith criticism to Egyptology, the Muslim world built the foundations upon which modern knowledge rests. Western historians, secular scholars, atheist philosophers, and even the institutions of NASA and the Library of Congress have confirmed what Islamic theology always demanded: that knowledge is worship, and that the created world is a book to be read.
