It was narrated from Ibn 'Abbas that a man came to the Prophet who had declared Zihar from his wife, then he had intercourse with her. He said:
"O Messenger of Allah, I declared Zihar on my wife, then I had intercourse with her before I offered the expiation." He said: "What made you do that, may Allah have mercy on you?" He said: "I saw her anklets in the light of the moon." He said: "Do not approach her until you have done that which Allah, the Mighty and Sublime, has commanded."
