حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مَسْلَمَةَ الْقَعْنَبِيُّ، عَنْ مَالِكٍ، عَنِ ابْنِ شِهَابٍ، عَنْ عُبَيْدِ اللَّهِ بْنِ عَبْدِ اللَّهِ بْنِ عُتْبَةَ بْنِ مَسْعُودٍ، عَنْ أُمِّ قَيْسٍ بِنْتِ مِحْصَنٍ، أَنَّهَا أَتَتْ بِابْنٍ لَهَا صَغِيرٍ لَمْ يَأْكُلِ الطَّعَامَ إِلَى رَسُولِ اللَّهِ صلى الله عليه وسلم فَأَجْلَسَهُ رَسُولُ اللَّهِ صلى الله عليه وسلم فِي حِجْرِهِ فَبَالَ عَلَى ثَوْبِهِ فَدَعَا بِمَاءٍ فَنَضَحَهُ وَلَمْ يَغْسِلْهُ ‏.‏
