Mukhtasar Bukhari (Abridged) 1273 — Taking pledge in battle not

Narrated Salama bin Al-Akwa’ (may Allah be pleased with him): I gave the pledge of allegiance to the Messenger of Allah (peace and blessings be upon him) (at the event of the Pledge of Ridwan). After that, I went towards the shade of a tree. When the crowd of people lessened, the Prophet (peace and blessings be upon him) said: “O Ibn Akwa’! Will you not give the pledge?” I said, “O Messenger of Allah! I have already given the pledge.” He (peace and blessings be upon him) said: “Even so (do it again).” So I gave the pledge to him again. It was asked, “Abu Muslim (this is the kunyah of Salama bin Al-Akwa’), on what did you pledge allegiance that day?” He said: “On death.”
