Musannaf Ibn Abi Shaybah 39746 — What I have preserved

Yahya bin Abbad bin Abdullah bin al-Zubayr narrates from his father, from his grandfather, that he said: The man of Banu Murrah who suckled me (that is, whose wife suckled me) told me, and he said: It is as if I am looking at Sayyiduna Ja'far (may Allah be pleased with him) at the Battle of Mu'tah. He dismounted from his reddish-white horse, then hamstrung it, then went on and fought until he was killed (martyred).
