حَدَّثَنَا أَحْمَدُ بْنُ عَبْدَةَ، أَنْبَأَنَا حَمَّادُ بْنُ زَيْدٍ، حَدَّثَنَا ثَابِتٌ، عَنْ أَنَسٍ، أَنَّ أَعْرَابِيًّا، بَالَ فِي الْمَسْجِدِ فَوَثَبَ إِلَيْهِ بَعْضُ الْقَوْمِ فَقَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ " لاَ تُزْرِمُوهُ " . ثُمَّ دَعَا بِدَلْوٍ مِنْ مَاءٍ فَصَبَّ عَلَيْهِ .
