A Bedouin came and urinated in a corner of the mosque

Harshness and ignorance are natural habits of the Bedouins because they live in isolation from learning what Allah, the Almighty, revealed unto His Messenger (may Allah's peace and blessings be upon him). Once, while the Prophet (may Allah's peace and blessings be upon him) was with his Companions in the mosque, a Bedouin entered and urinated in one corner of the mosque assuming it was an open space. His action offended the Companions (may Allah be pleased with them), due to the mosque's sanctity. As a result, they rebuked him while he was urinating.

Knowing the habits of the Bedouins, however, the Prophet (may Allah's peace and blessings be upon him) who was sent with ease and glad tidings ordered them to stop rebuking him, otherwise he would urinate on a larger spot in the mosque, or make his clothes impure, and to avoid harm had he been interrupted during passing urine. Moreover, he would be more inclined that way to accept the advice of the Prophet (may Allah's peace and blessings be upon him) when he advises him. He ordered them to purify the place where he urinated by pouring a bucket of water over it.
