Narrated Aisha: The wife of Rifa`a Al-Qurazi came to the Prophet and said, I was Rifa`a's wife, but he divorced me and it was a final irrevocable divorce. Then I married `Abdur-Rahman bin Az-Zubair but he is impotent. The Prophet asked her 'Do you want to remarry Rifa`a? You cannot unless you had a complete sexual relation with your present husband. Abu Bakr was sitting with Allah's Apostle and Khalid bin Sa`id bin Al-`As was at the door waiting to be admitted. He said, O Abu Bakr! Do you hear what this (woman) is revealing frankly before the Prophet ?
