The Lineage of the Prophet Muhammad ﷺ — Established from Heritage Books and Refuting the "4-Year Pregnancy
The lineage of the Prophet Muhammad ﷺ is documented without disagreement in the books of biography and history from the earliest generations. Those who question it ignore the testimony of his own uncles — some of whom protected him without believing, some of whom believed and supported him, and some of whom disbelieved and opposed him — and yet none of them doubted his lineage to their brother. The same applies to the disbelievers despite their slander of him in other matters.
The Established Lineage to Adnan
There is no disagreement about the lineage of the Prophet ﷺ to his grandfather Adnan. It is as follows:
Muhammad ibn Abdullah ibn Abdul Muttalib ibn Hashim ibn Abdul Manaf ibn Qusay ibn Kilab ibn Murrah ibn Ka’ab ibn Lu’ay ibn Ghalib ibn Fihr ibn Malik ibn al-Nadr ibn Kinanah ibn Khuzaymah ibn Mudrikah ibn Ilyas ibn Mudar ibn Nizar ibn Ma’ad ibn Adnan.


The lineage is documented across 108 proofs in the detailed genealogy study. The following sources confirm the chain:




Refuting the “4-Year Pregnancy” Fabrication
The Weakness of Al-Waqidi’s Narration
Al-Waqidi‘s hadith is abandoned (matruk) — his narrations are not accepted as evidence. The narration in question is also interrupted in its chain, and its narrators are unknown.
Furthermore, Al-Waqidi himself transmitted another narration that contradicts the claim — stating that Hamza and Al-Abbas were born before the marriage of Abdullah ibn Abdul Muttalib. The deceivers selected the narration that served their purpose and ignored the contradicting narration from the same abandoned source.




The fabricators constructed a story with no basis — that Abdullah entered upon Amina when he became her husband — while ignoring other stories of the same level that contradict this. The books of biography transmit stories, leaving their verification to the scholars of hadith. It is not permissible to take these stories as established facts without the authentication of the hadith scholars.




The Quran Establishes the Minimum Pregnancy Duration as Six Months
What is mentioned in the Quran is a minimum pregnancy duration of six months:
“And his gestation and weaning is thirty months.”
As for Imam Malik‘s opinion that pregnancy may last for up to four years — this was stated in the context of not accusing a woman of fornication, based on the principle of warding off legal penalties with doubts (“ward off the limits with doubts”). He witnessed a case like that — the wife of Muhammad ibn Ajlan — where she “felt” that her pregnancy would last for four years and gave birth to three children in twelve years. There is no way to verify such a claim medically now.




The Lineage of the Prophet ﷺ to Ismail Son of Ibrahim (Peace Be Upon Them)
As for the lineage of the Prophet ﷺ to Ismail son of Ibrahim (peace be upon them) — the genealogists have confirmed it. This is acknowledged by the historian and father Gregory Abu al-Faraj — known as Ibn al-‘Ibri — a Christian historian whose acknowledgment carries particular weight as an external confirmation.
