question #3 Sahih al-Bukhari 5368, Book 69, Hadith 18 : What is the significance of charity in the context of expiation for breaking a fast during Ramadan?

A man came to the Prophet (ﷺ) and said, “I am ruined!” The Prophet (ﷺ) said, “Why?” He said, “I had sexual
intercourse with my wife while fasting (in the month of Ramadan).” The Prophet (ﷺ) said to him,
“Manumit a slave (as expiation).” He replied, “I cannot afford that.” The Prophet (ﷺ) said, “Then fast for
two successive months.” He said, “I cannot.” The Prophet (ﷺ) said, “Then feed sixty poor persons.” He
said, “I have nothing to do that.” In the meantime a basket full of dates was brought to the Prophet (ﷺ) .
He said, “Where is the questioner.” The man said, “I am here.” The Prophet (ﷺ) said (to him), “Give this
(basket of dates) in charity (as expiation).” He said, “O Allah’s Messenger (ﷺ)! Shall I give it to poorer
people than us? By Him Who sent you with the Truth, there is no family between Medina’s two
mountains poorer than us.” The Prophet (ﷺ) smiled till his pre-molar teeth became visible. He then said,
“Then take it.”
