Narrated `Abdullah bin `Umar: Allah's Apostle and Ubai bin Ka`b Al-Ansari went to the garden where Ibn Saiyad used to live. When Allah's Apostle entered (the garden), he (i.e. Allah's Apostle ) started hiding himself behind the date108 palms as he wanted to hear secretly the talk of Ibn Saiyad before the latter saw him. Ibn Saiyad wrapped with a soft decorated sheet was lying on his bed murmuring. Ibn Saiyad's mother saw the Prophet hiding behind the stems of the date-palms. She addressed Ibn Saiyad saying, "O Saf, this is Muhammad." Hearing that Ibn Saiyad stopped murmuring (or got cautious), the Prophet said, "If she had left him undisturbed, he would have revealed his reality." (See Hadith No. 290, Vol 4 for details)

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 ?"
