Sunan al-Nasa'i
The Book of Purification — Hadith #53
أَخْبَرَنَا قُتَيْبَةُ، قَالَ حَدَّثَنَا حَمَّادٌ، عَنْ ثَابِتٍ، عَنْ أَنَسٍ، أَنَّ أَعْرَابِيًّا، بَالَ فِي الْمَسْجِدِ فَقَامَ إِلَيْهِ بَعْضُ الْقَوْمِ فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم
" دَعُوهُ لاَ تُزْرِمُوهُ " . فَلَمَّا فَرَغَ دَعَا بِدَلْوٍ فَصَبَّهُ عَلَيْهِ . قَالَ أَبُو عَبْدِ الرَّحْمَنِ يَعْنِي لاَ تَقْطَعُوا عَلَيْهِ .
“Leave him and do not restrain him.” When he had finished he called for a bucket (of water) and poured it over it.
Abu ‘Abdur-Rahman (An-Nasa’i) said: “Meaning: ‘Do not interrupt him.'”
The author will cite this narration again in No. 330 as a possible proof for setting the minimum, since it mentions “a bucket” as if this is the minium amount required.
