ʿAbdullāh ibn Abī Awfā (may Allah be pleased with him) reported: We came upon donkeys leaving the village, and the Messenger of Allah (ﷺ) ﷺ said, “Empty out the cooking pots, and all.” I mentioned this to Saʿīd ibn Jubayr, who said, “He only forbade them because they used to eat filth.” Reference: Musnad Aḥmad 228
