Musannaf Ibn Abi Shayba 7:423

Ibn ‘Uyaynah narrated to us, from al-Zuhri, from Humayd ibn ‘Abd al-Rahman, from Abu Hurayrah, who said: A man came to the Prophet, may Allah bless him and grant him peace, and said: "I am ruined." He said: "And what has ruined you?" He said: "I had intercourse with my wife during Ramadan." The Prophet, may Allah bless him and grant him peace, said: "Free a slave." He said: "I do not find one." He said: "Then fast two consecutive months." He said: "I am not able." He said: "Then feed sixty poor people." He said: "I do not find [the means]." He said: "Sit." So he sat. While he was in that state, a basket containing dates was brought. The Prophet, may Allah bless him and grant him peace, said to him: "Go and give this as charity." He said: "O Messenger of Allah, by the One who sent you with the truth, there is no household between its two lava fields [of Medina] more in need than us." The Prophet, may Allah bless him and grant him peace, laughed until his canine teeth appeared, then said: "Go and feed it to your family."
