Mukhtasar Bukhari (Abridged) 166 — Prophet and companions allowing

Narrated Abu Huraira (may Allah be pleased with him): A Bedouin stood up and began to urinate in the mosque. The people wanted to attack him (i.e., beat him), but the Prophet (peace and blessings of Allah be upon him) said to them: "Leave him alone and pour a bucket of water over his urine, for you have been sent to make things easy, not to make things difficult."
