And Bishr ibn Khalid narrated to me, saying: Muhammad—meaning Ibn Ja'far—narrated to us from Shu'bah, who said: I heard Sulayman, who said: I heard Abu Sufyan, who said: I heard Jabir ibn 'Abdullah, who said: Ubayy was struck on the day of al-Ahzab on his median cubital vein, and the Messenger of Allah, peace and blessings be upon him, cauterized it.
