"The Messenger of Allah ﷺ was asked about water and how some animals and carnivorous beasts might drink from it. He said: 'If the water is more than two Qullahs, it will not become filthy.'"  

سُئِلَ رَسُولُ اللَّهِ ﷺ عَنِ الْمَاءِ وَمَا يَنُوبُهُ مِنَ الدَّوَابِّ وَالسِّبَاعِ فَقَالَ إِذَا كَانَ الْمَاءُ قُلَّتَيْنِ لَمْ يَحْمِلِ الْخَبَثَ  

"Do not restrain him." When he had finished he called from a bucket (of water) and poured over it.  

أَنَّ أَعْرَابِيًّا بَالَ فِي الْمَسْجِدِ فَقَامَ إِلَيْهِ بَعْضُ الْقَوْمِ فَقَالَ رَسُولُ اللَّهِ ﷺ لاَ تُزْرِمُوهُ فَلَمَّا فَرَغَ دَعَا بِدَلْوٍ مِنْ مَاءٍ فَصَبَّهُ عَلَيْهِ  

"A Bedouin stood up and urinated in the Masjid, so the people grabbed him. The Messenger of Allah ﷺ said to them: 'Leave him alone, and pour a bucket of water over his urine. For you have been sent to make things easy for people, you have not been sent to make things difficult.'"  

قَامَ أَعْرَابِيٌّ فَبَالَ فِي الْمَسْجِدِ فَتَنَاوَلَهُ النَّاسُ فَقَالَ لَهُمْ رَسُولُ اللَّهِ ﷺ دَعُوهُ وَأَهْرِيقُوا عَلَى بَوْلِهِ دَلْوًا مِنْ مَاءٍ فَإِنَّمَا بُعِثْتُمْ مُيَسِّرِينَ وَلَمْ تُبْعَثُوا مُعَسِّرِينَ
