Narrated `Aisha: The wife of Rifa`a Al-Qurazi came to Allah's Apostle and said, O Allah's Apostle! Rifa`a divorced me irrevocably. After him I married `Abdur-Rahman bin Az-Zubair Al-Qurazi who proved to be impotent. Allah's Apostle said to her, Perhaps you want to return to Rifa`a? Nay (you cannot return to Rifa`a) until you and `Abdur-Rahman consummate your marriage.
