Ishaq bin Abdullah narrates from his uncle, Sayyiduna Anas bin Malik (may Allah be pleased with him): The Prophet Muhammad (peace be upon him) was sitting in the mosque. During this time, a Bedouin came in and began to urinate while sitting. The companions of the Prophet (peace be upon him) said: Stop, stop! The Prophet (peace be upon him) said: Do not try to stop him while he is urinating. Then the Prophet (peace be upon him) called that person and said: It is not appropriate to bring impurity or relieve oneself inside these mosques, or whatever else the Prophet (peace be upon him) said. The Qur'an is recited here, or Allah is remembered here. Then the Prophet (peace be upon him) called for a bucket of water and poured it over the spot.
