Musnad Imam Shafi'i

Saeed bin Musayyib (may Allah have mercy on him) narrates that a Bedouin came to the Messenger of Allah ﷺ, he was pulling out his hair and beating his chest, and saying: and he was beating his chest and saying: "Separation has destroyed me." The Messenger of Allah ﷺ asked: "What happened?" He said: "I had intercourse with my wife while fasting in Ramadan." The Messenger of Allah ﷺ asked: "Do you have the ability to free a slave?" He said: "No." He ﷺ asked: "Do you have the ability to sacrifice a camel?" He said: "No." He ﷺ said: "Alright, sit down." Saeed bin Musayyib (may Allah have mercy on him) says that a large bag of dates was presented to the Messenger of Allah ﷺ, and he ﷺ said: "Take this and give it in charity." The man said: "I do not find anyone more needy than myself." He ﷺ said: "Eat it, and fast another day in place of that (intercourse) day." Ata (may Allah have mercy on him) says: I asked Saeed bin Musayyib (may Allah have mercy on him): "How many dates were in that bag?" He replied: "Between 15 and 20 sa’."
