سنن أبي داود

Jabir b. Samurah said: I saw Ma’iz b. Malik when he was brought to the Prophet (ﷺ). He was a small and muscular man. He did not wear the loose outer garment. He made confession about him four times that he committed fornication. The Messenger of Allah (ﷺ) said: Perhaps you kissed her. He said that this most discarded man has committed fornication. He said: So he had him stoned to death and gave an address, saying: Beware, whenever we go out on an expedition in the path of Allah, one of them (I.e. the people) lags behind with a bleating sound like that of a he-goat, and gives modicum of his milk(i.e. sperm) to one of the women. If Allah gives control over any of them, I shall deter him from them (i.e. women) by punishing him severely.
