Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) narrates: A man came to the Prophet (peace and blessings be upon him) who had pronounced zihar on his wife and then had intercourse with her. He said: "O Messenger of Allah, I pronounced zihar on my wife, and then I had intercourse with her before offering the expiation." He (peace and blessings be upon him) said: "May Allah have mercy on you, what led you to do that?" He said: "I saw her anklet in the light of the moon." He (peace and blessings be upon him) said: "Then do not go near her until you have done what Allah, the Mighty and Majestic, has commanded you."
