Yahya related to me from Malik, from Abu'n-Nadr, the mawla of'Umar ibn 'Ubaydullah at-Taymi, from Nafi, the mawla of Abu Qatada al-Ansari, that Abu Qatada was once with the Messenger of Allah, mayAllah bless him and grant him peace. When they got to one of the roadsto Makka he fell behind with some companions of his who were muhrim,while he was not. Then he saw a wild ass, so he got on his mount andasked his companions to give him his whip but they refused. Then heasked them for his spear and they refused to give it to him. So hetook hold of it and attacked the ass and killed it. Some of thecompanions of the Messenger of Allah, may Allah bless him and granthim peace, ate from it, and others refused. When they had caught upwith the Messenger of Allah, may Allah bless him and grant him peace,they asked him about it and he said, "It is food that Allah has fedyou with."
