It was narrated from 'Ubaidullah bin 'Abdullah bin 'Umar that his father said: 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.'
It was narrated from Anas that a Bedouin urinated in the Masjid, and some of the people went after him, but the Messenger of Allah (ﷺ) said: Do not restrain him. When he had finished he called from a bucket (of water) and poured over it.
It was narrated that Abu Hurairah said: 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.'
