What did the Prophet Muhammad (saw) do when a bedouin urinated in the mosque?
 Narrated Anas bin Malik:                     A bedouin urinated in the mosque and the people ran to (beat) him. Allah's Apostle said, "Do not interrupt his urination (i.e. let him finish)." Then the Prophet asked for a tumbler of water and poured the water over the place of urine.
