Ja’far ibn Ali ibn Abi Talib (Arabic: جعفر بن علي بن أبي طالب) was son of Imam Ali and Umm ul-Banin. He was present with Imam Hussain in (the battle of) Karbala as one of his companions. Imam Ali named him Jafar because of his great love for Ja’far ibn Abi Talib who was his brother. Finally, he was martyred on Ashurawith his brothers Abbas, Abdullah and Uthman
Martyrdom of Ja’far bin Ali bin Abi Talib
He fought bravely, and according to Manaqib was saying, “Verily I am Ja’far the possessor of excellence, the son of Ali the bestower, the successor to the Prophet a senior and master, I am in proportionate to my (paternal) uncle Ja’far as also my maternal uncle, I defend Husayn the possessor of generosity and grace”. Hani bin Sabeet attacked him and killed him. (May Allah’s Mercy and Blessings be upon him).
Abul Faraj quotes Imam Muhammad al Baqir (a.s.) saying,
“Khawli Asbahi killed him”.
Ibn Shahr Ashob says that Khawli Asbahi shot an arrow that pierced his temple or his eye.
