Al-Adab Al-Mufrad #227

Abu Dharr reported that it was said, "Messenger of Allah, the wealthy people have taken all the rewards. They pray as we pray. They fast as we fast, but they give sadaqa from their excess wealth." He said, "Has Allah not given you something to give as sadaqa? Every time you praise or glorify Allah, that is sadaqa. There is sadaqa is sexual intercourse." He was asked, "Is there sadaqa in satisfying one's appetite?" He replied, "If he does it in a haram manner, is that not a wrong action? Similarly if he does it in a halal manner, he receives a reward."
