Sunan an-Nasa'i 3459

Ikrimah said:"A man came to the Prophet of Allah and said: 'O Prophet of Allah,' and that he had declared Zihar to his wife, then he had intercourse with her before he did what he had to do. He said: 'What made you do that?' He said: 'O Prophet of Allah! I saw the whiteness of her calves in the moonlight.' The Prophet said: 'Keep away until you have done what you have to do.' (One of the narrators) Ishaq said in his Hadith: "Keep away from her until you have done what you have to do." The wording is that of Muhammad
