Abd Allah ibn Muhammad al-Baqir

Abd Allah ibn Muhammad al-Baqir, Peace Be Upon Him, belonged to the Husaynid branch of the Ahl al-Bayt. His father was Imam Muhammad ibn Ali al-Baqir, Peace Be Upon Him, and his mother was Umm Farwa Fatima bint al-Qasim ibn Muhammad ibn Abi Bakr. The same mother was the mother of Imam Ja'far al-Sadiq, so Abd Allah and Imam al-Sadiq were full brothers. This parentage is preserved in the child list attributed to Shaykh al-Mufid and in later Imami biographical works.

Later biographical notices give the name variants Daqdaq and Duraq and suggest a birth in Medina in 84 or 85 AH. These particulars are not presented as equally early or certain. The stronger biographical point is that he was known as a Medinan member of Imam al-Baqir's household and lived into the period of his brother Imam al-Sadiq.

Shaykh al-Mufid describes Abd Allah as a person indicated for merit and righteousness. Shaykh al-Tusi also lists an Abd Allah ibn Muhammad ibn Ali ibn al-Husayn among the Medinan companions of Imam al-Sadiq. The surviving notices do not preserve an extensive independent teaching career, a large body of transmitted sayings, or a public political office for him, so the profile does not expand these brief evaluations into an unsupported scholarly biography.

Al-Mufid and Abu al-Faraj al-Isfahani preserve a report that Abd Allah entered the presence of an Umayyad man who intended to kill him. Abd Allah appealed to the man not to commit the killing, but the man rejected his appeal and later gave him poison in a drink. The report establishes an early Imami and Talibid memory of death by poisoning, but it does not securely name the Umayyad official or provide a precise date and place in the quoted passage.

Genealogical and later biographical works disagree about whether Abd Allah left descendants. Some later reports name sons and daughters, while other genealogical statements restrict the continuing line of Imam al-Baqir to Imam al-Sadiq. Because no strong, fully reconciled spouse record was found and the administrative relationship fields were blank, no spouse or child relationship has been created in this person file.

A later biographical tradition places Abd Allah's death around 115 AH in Medina, reports that Sa'id ibn al-Musayyib led the funeral prayer, and associates his burial with al-Baqi. These details are retained as later reports rather than as facts of the same strength as his parentage and the poisoning account. No separate shrine or GPS link was supplied, and none has been invented.
