Mishkat al-Masabih 3215

Abdallah ibn Amr told that a steward of his came to him and he asked him whether he had given the slaves their food. When he replied that he had not, he told him to go and give it to them, for God’s Messenger had said, “It is a serious enough fault for a man to withhold his food from one whom he possesses.” A version has, “It is a serious enough fault for a man to destroy one he is bound to sustain.”
