Narrated Abu Huraira: A bedouin urinated in the mosque, and the people rushed to beat him. Allah's Apostle ordered them to leave him and pour a bucket or a tumbler (full) of water over the place where he has passed urine. The Prophet then said, " You have been sent to make things easy (for the people) and you have not been sent to make things difficult for them."
— Sahih Bukhari, Volume 8, Book 73: Good Manners and Form (Al-Adab), Hadith #149
