A man came to the Prophet (ﷺ) and said that he had been burnt (ruined). The Prophet (ﷺ) asked him what was the matter. He replied, "I had sexual intercourse with my wife in Ramadan (while I was fasting)." Then a basket full of dates was brought to the Prophet (ﷺ) and he asked, "Where is the burnt (ruined) man?" He replied, "I am present." The Prophet (ﷺ) told him to give that basket in charity (as expiation).
Sahih al-Bukhari Book 30, Hadith 42
← Previous Hadith I saw `Uthman performing ablution; he washed his hands thrice, rinsed his mouth and then washed his nose, by putting water in it and then blowing it out, and washed his face thrice, and then washed his right forearm up to the elbow thrice, and then the left-forearm up to the elbow thrice, then smeared his head with water, washed his right foot thrice, and then his left foot thrice and said, "I saw Allah's Apostle performing ablution similar to my present ablution, and then he said, 'Whoever performs ablution like my present ablution and then offers two rak`at in which he does not think of worldly things, all his previous sins will be forgiven."

Sahih al-Bukhari Book 30, Hadith 41 Next Hadith → While we were sitting with the Prophet (ﷺ) a man came and said, "O Allah's Messenger (ﷺ)! I have been ruined." Allah's Messenger (ﷺ) asked what was the matter with him. He replied "I had sexual intercourse with my wife while I was fasting." Allah's Messenger (ﷺ) asked him, "Can you afford to manumit a slave?" He replied in the negative. Allah's Messenger (ﷺ) asked him, "Can you fast for two successive months?" He replied in the negative. The Prophet (ﷺ) asked him, "Can you afford to feed sixty poor persons?" He replied in the negative. The Prophet (ﷺ) kept silent and while we were in that state, a big basket full of dates was brought to the Prophet (ﷺ) . He asked, "Where is the questioner?" He replied, "I (am here)." The Prophet (ﷺ) said (to him), "Take this (basket of dates) and give it in charity." The man said, "Should I give it to a person poorer than I? By Allah; there is no family between its (i.e. Medina's) two mountains who are poorer than I." The Prophet (ﷺ) smiled till his premolar teeth became visible and then said, 'Feed your family with it."
