محمد الباقر
Abu Jafar
Abu Jafar Muhammad ibn Ali ibn al-Husayn, known as Muhammad al-Baqir, was an eminent Medinan scholar of the late first and early second Islamic centuries and is recognized by Twelver Shiism as the fifth Imam and by Ismaili tradition as the fourth. He was the son of Ali Zayn al-Abidin and Fatima bint Hasan, making him a descendant of Husayn through his father and Hasan through his mother. He was born in Medina, most commonly placed in 57 AH / 676–677 CE, and was a small child at Karbala. He learned extensively from his father and transmitted from senior Medinan authorities including Jabir ibn Abd Allah, Ibn Umar, Abu Said al-Khudri and Said ibn al-Musayyib; he also transmitted mursal reports from earlier Companions whom he could not have met. Sunni and Shiʿi sources agree on his high scholarly standing but preserve sharply different pictures of his doctrines and role. Later Imami and Ismaili tradition gives him a foundational place in the doctrine of imamate and in Shiʿi law, theology and Qurʾanic interpretation, while Sunni hadith critics remember him as a trustworthy Medinan transmitter and jurist. He followed his father’s generally non-insurrectionary political posture and is reported to have disagreed with or cautioned his brother Zayd about revolt. Stories of debates with Abu Hanifa and other opponents vary by confessional source and sometimes contain chronological impossibilities. His death date is genuinely disputed: 114 AH / 732–733 is the dominant later Imami date, while early historical reports of 117 AH / 735 and 118 AH / 736 have been judged chronologically plausible by modern scholarship. He was buried in al-Baqi in Medina. Later poisoning narratives are inconsistent and include anachronistic versions, so poisoning cannot be treated as established fact.
