حَدَّثَنَا عَلِيُّ بْنُ مُحَمَّدٍ، حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ عَبْدِ اللَّهِ، حَدَّثَنَا حَمَّادُ بْنُ سَلَمَةَ، عَنْ أَبِي هَاشِمٍ الرُّمَّانِيِّ، عَنْ حَبِيبِ بْنِ أَبِي ثَابِتٍ، عَنْ أُمِّ سَلَمَةَ، أَنَّ النَّبِيَّ ـ صلى الله عليه وسلم ـ كَانَ إِذَا اطَّلَى بَدَأَ بِعَوْرَتِهِ فَطَلاَهَا بِالنُّورَةِ وَسَائِرَ جَسَدِهِ أَهْلُهُ ‏.‏
