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 ‏.‏
Translation
Anas said

"A Bedouin came to the Masjid and urinated, and the people yelled at him, but the Messenger of Allah (ﷺ) said: 'Leave him alone.' So they left him alone. When he had finished urinating, he ordered that a bucket (be brought) and poured over it."
