From Sahih Muslim (Hadith 2601):
A'isha (Allah be pleased with her) reported that a person came to the Messenger of Allah (ﷺ) and said:I am burnt, whereupon the Messenger of Allah (ﷺ) said: How is it? He (the person) said: I had intercourse with my wife during the day in Ramadan. Upon this (the Holy Prophet) said: Give charity, give charity. He (the person) said: There is nothing with me. He commanded him to sit down, (In the meanwhile) there were brought to him (to the Holy Prophet) two baskets containing eatables, whereupon the Messenger of Allah (ﷺ) told him to give them as sadaqa
