Abdullah bin Abi Qatadah was informed by his father that he took part with the Prophet (peace and blessings be upon him) in the expedition of Hudaybiyah. (He said:) Everyone except me entered ihram for Umrah. I hunted a wild ass and fed it to my companions, who were in ihram. Then I came and informed the Prophet (peace and blessings be upon him) that we had some meat left over. He (peace and blessings be upon him) said: "Eat it," while they were all in ihram.
(b) Abu Muhammad, the freed slave of Abu Qatadah (may Allah be pleased with him), narrates from Abu Qatadah (may Allah be pleased with him): We set out with the Messenger of Allah (peace and blessings be upon him), and when we reached the place called al-Qahah, some of us were in ihram and some were not.
