He went on the expedition of Hudaybiyyah with the Messenger of Allah ﷺ. He said, "They all entered the state of ihram for Amra except me. I hunted a wild donkey and fed my companions from it while they were in ihram. Then I came to the Messenger of Allah ﷺ and informed him that we had some of its meat left over. He said, 'Eat it,' even though they were in ihram."
أخبرني عبيد الله بن فضالة بن إبراهيم النسائي قال أنبأنا محمد وهو ابن المبارك الصوري قال حدثنا معاوية وهو ابن سلام عن يحيى بن أبي كثير قال أخبرني
أنه غزا مع رسول الله ﷺ غزوة الحديبية قال فأهلوا بعمرة غيري فاصطدت حمار وحش فأطعمت أصحابي منه وهم محرمون ثم أتيت رسول الله ﷺ فأنبأته أن عندنا من لحمه فاضلة فقال كلوه وهم محرمون
