What was the Prophet Muhammad (peace be upon him) asked by the wife of Rifa'a Al-Qurazi when she came to him?
 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 ?"
