Narrated AbuDharr:

The Prophet (ﷺ) said: In the morning alms are due from every bone in man's fingers and toes. Salutation to everyone he meets is alms; enjoining good is alms; forbidding what is disreputable is alms; removing what is harmful from the road is alms; having sexual intercourse with his wife is alms. The people asked: He fulfils his desire, Messenger of Allah; is it alms? He replied: Tell me if he fulfilled his desire where he had no right, would he commit a sin ? He then said: Two rak'ahs which one prays in the forenoon serve instead of all that. Abu Dawud said: Hammad did not mention enjoining good and forbidding what is disreputable.
