Musannaf Ibn Abi Shayba 16:108

Abu Bakr narrated to us, he said: Shareek narrated to us, from Mansur, from Ubayd ibn al-Hasan, from Ghalib ibn Abjar, who said: I said: "O Messenger of Allah, a year of drought has afflicted us, and I have no wealth except donkeys." He said: "Eat from your wealth, for I only disliked them because of the refuse of the village."
