Jami` at-Tirmidhi 3306
Ma’mar narrated from Az-Zuhri, from Urwah that Aishah said:
“The Messenger of Allah would not have examined  (the women) except for the Ayah in which Allah said: When believing come to you pledging to you.” Ma’mar said: “Ibn Tawus informed me from his father who said: ‘The hand of the Messenger of Allah did not touch the hand of a women he had not acquired.’”
حَدَّثَنَا عَبْدُ بْنُ حُمَيْدٍ، حَدَّثَنَا عَبْدُ الرَّزَّاقِ، عَنْ مَعْمَرٍ، عَنِ الزُّهْرِيِّ، عَنْ عُرْوَةَ، عَنْ عَائِشَةَ، قَالَتْ مَا كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم يَمْتَحِنُ إِلاَّ بِالآيَةِ الَّتِي قَالَ اللَّهُ ‏:‏ ‏(‏إذَا جَاءَكَ الْمُؤْمِنَاتُ يُبَايِعْنَكَ ‏)‏ الآيَةَ ‏.‏ 

 قَالَ مَعْمَرٌ فَأَخْبَرَنِي ابْنُ طَاوُسٍ، عَنْ أَبِيهِ، قَالَ مَا مَسَّتْ يَدُ رَسُولِ اللَّهِ صلى الله عليه وسلم يَدَ امْرَأَةٍ إِلاَّ امْرَأَةً يَمْلِكُهَا ‏.‏ قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ ‏.‏
