Musannaf Ibn Abi Shaybah 10035 — A man who breaks his fast for a day

Sa'id bin al-Musayyib says: A man came to the Prophet (peace and blessings be upon him) and said: "I have broken one fast of Ramadan. What is the ruling for me now?" The Prophet (peace and blessings be upon him) said: "Give charity, seek forgiveness from Allah, and fast one day in its place."
