Sayyiduna Abu Qatadah al-Ansari (may Allah be pleased with him) says that he was with the Prophet (peace and blessings be upon him) on one of the roads to Makkah. He stayed behind with some companions of his who were in ihram, while he himself was not in ihram. He saw a wild ass, settled firmly on his horse, and asked his companions to hand him his whip, but they refused. He asked for his spear, and again they refused. Then Sayyiduna Abu Qatadah (may Allah be pleased with him) took his spear himself and rode, chased the wild ass and killed it. Some of the Companions (may Allah be pleased with them) ate from it and some refused to eat. When they came to the Prophet (peace and blessings be upon him), they asked him (peace and blessings be upon him) about it, and he (peace and blessings be upon him) said: "It is but food that Allah, the Lord of Might, has fed you."
