Hadith 4744
Iyas bin Salamah bin Akwa’ narrates from his father: I participated in that battle along with Sayyiduna Abu Bakr (may Allah be pleased with him) in which the Prophet Muhammad (peace and blessings be upon him) appointed Sayyiduna Abu Bakr (may Allah be pleased with him) as our leader and sent him with us. We attacked some polytheists at night and killed them. At that time, our slogan (or identifying cry) was: “Kill! Kill!” The narrator states: That night, I killed members of the households of the polytheists with my own hands.
