حَدَّثَنَا مُحَمَّدُ بْنُ عَبْدِ اللَّهِ بْنِ نُمَيْرٍ، حَدَّثَنَا عُمَرُ بْنُ عُبَيْدٍ الطَّنَافِسِيُّ، حَدَّثَنَا عُمَرُ بْنُ الْمُثَنَّى، عَنْ عَطَاءٍ الْخُرَاسَانِيِّ، عَنْ أَنَسِ بْنِ مَالِكٍ، قَالَ كُنْتُ مَعَ رَسُولِ اللَّهِ ـ صلى الله عليه وسلم ـ فِي سَفَرٍ فَقَالَ ‏"‏ هَلْ مِنْ مَاءٍ ‏"‏ ‏.‏ فَتَوَضَّأَ وَمَسَحَ عَلَى خُفَّيْهِ ثُمَّ لَحِقَ بِالْجَيْشِ فَأَمَّهُمْ ‏.‏
