Washing off urine in the mosque

 186. Anas bin Malik narrated: While we were in a mosque with Messenger of Allah salla alayhi wa sallam, a bedouin came and and began to urinate in the mosque. The Companions of the Messenger of Allah salla alayhi wa sallam said: ´´Stop, stop;´´ but the Messenger of Allah salla alayhi wa sallam said: ´´Don´t interrupt him; leave him alone.´´ They let him, and when he finished urinating, the Messenger of Allah salla alayhi wa sallam called him and said to him: ´´These mosques are not places for urinating and filth, but are only for the remebrance of allah, praying and the recitation of the Qur´an,´´ or as the Messenger of Allah salla alayhi wa sallam said somthing like that. He said that the Prophet salla alayhi wa sallam ordered a man who brought a bucket of water and poured it over.
