Mishkat al-Masabih 3302

‘Ikrima told on the authority of Ibn ‘Abbas that a man who had vowed to make his wife like his mother’s back had intercourse with her before making atonement, so he went to the Prophet (ﷺ) and mentioned that to him. He asked him what had induced him to do that and he replied, “Messenger of God, I saw the whiteness of her silver anklets in the moonlight and could not restrain myself from having intercourse with her.” God's Messenger laughed and ordered him not to go near her till he had made atonement. Ibn Majah transmitted it, and Tirmidhi transmitted something similar, saying this is a hasan sahih gharib tradition. Abu Dawud and Nasa’i transmitted something similar both with a full isnad and in mursal form, Nasa’i saying that the mursal version is nearer the truth than the one with a full isnad.
