Zuhayr ibn Harb narrated to me: Marwan ibn Mu'awiyah al-Fazari narrated to us: Yazid ibn Kaysan informed us, from Abu Hazim, from Abu Hurayrah, who said: A man stayed late with the Prophet, peace and blessings be upon him, then returned to his family and found that the children had already fallen asleep. His family brought him his food, but he swore he would not eat because of his children. Then it occurred to him to eat, so he ate. He came to the Messenger of Allah, peace and blessings be upon him, and mentioned that to him. The Messenger of Allah, peace and blessings be upon him, said: "Whoever swears an oath and then sees something better than it, let him do that better thing and expiate for his oath."
