That the Messenger of Allah (ﷺ) said that Jibra'il had indeed descended upon him to say to him: "Tell them - meaning your Companions - to choose regarding the captives of Badr, between either killing them or ransoming the, so that the amount killed by them will correspond similarly to them." So they said: "Ranson, even though some of us may be killed."
