Abdullah ibn Ja'far ibn Abi Talib al-Hashimi was the son of Ja'far al-Tayyar, the martyr of Mu'ta, and Asma bint Umays, and a nephew of Ali ibn Abi Talib. Born in Abyssinia during the migration and brought to Medina as a young child, he is reported to have been the last Hashimite Companion to have seen and kept company with the Prophet. He married Zaynab bint Ali, daughter of Ali and Fatima and granddaughter of the Prophet; his children included Ali, Awn, Abbas, and Umm Kulthum. Zaynab went to Karbala with her brother Husayn with his permission. He fought alongside Ali at the Battles of the Camel and Siffin. Regarded as the most generous Arab of his age and titled 'Bahr al-Jud' ('ocean of generosity'), his munificence became proverbial. According to the preferred view he died in 80 AH (699-700 CE) in Medina (variants give 84, 85, 86, 90). The governor of Medina, Aban ibn Uthman, attended his funeral and did not leave until he laid him in al-Baqi. He was buried in Jannat al-Baqi near the graves of Aqil ibn Abi Talib and Abu Sufyan ibn al-Harith. His burial place (Medina / al-Baqi) is undisputed.
