Musannaf Ibn Abi Shaybah 34379 — Reports on Jafar bin Abi Talib

Amir said: On the day of the Battle of Mu'tah, at a place called al-Balqa, Sayyiduna Ja'far (may Allah be pleased with him) was killed, and the Messenger of Allah (peace and blessings be upon him) supplicated: "O Allah, take the place of Ja'far among his family in the best way You have ever taken the place of any servant from among Your righteous servants."
