Ground that is soiled with urine and how it should be washed
Sunan Ibn Majah
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 .
It was narrated from Anas bin Malik that: A Bedouin urinated in the mosque, and some of the people rushed at him. The Messenger of Allah said: "Do not interrupt him." Then he called for a bucket of water and poured it over (the urine).
