Abdullah bin Abi Qatadah (may Allah have mercy on him) narrates from his father that he said: The Messenger of Allah (peace and blessings be upon him) set out for Hajj or Umrah, and we set out with him. He sent a group of them off by another route, and I was with them. He (peace and blessings be upon him) said: "Take the coastal route until you meet me." So we took the coastal route. When we turned back towards the Messenger of Allah (peace and blessings be upon him), all of them had entered ihram except Abu Qatadah (may Allah be pleased with him). While we were travelling, we suddenly saw some wild donkeys, and I brought down a female among them. They dismounted and ate of its meat, and said: "We are eating game meat while we are in the state of ihram!" They carried what remained of its meat until they came to the Prophet (peace and blessings be upon him) and said: We had entered ihram while Abu Qatadah had not; we saw some wild donkeys and he brought down a female among them; we dismounted and ate of its meat, then carried what remained of it. The Messenger of Allah (peace and blessings be upon him) asked: "Did any one of you tell him to attack it, or point to it?" They said: No. He (peace and blessings be upon him) said: "Then eat what remains of its meat."
