Musannaf Ibn Abi Shaybah

Hazrat Hisham states that Hasan Basri said: When a man accuses another man of involvement with a woman, he will be given two punishments of lashes—one punishment because of the man and the other because of the woman.

Hazrat Ubaidah says that Ibrahim stated: When a man says to another man, "Indeed, such-and-such person committed adultery with such-and-such woman," then only one punishment (hadd) will be applied to him.
