Musnad Ahmad Hadith 10533

It is narrated from Abu Huraira (may Allah be pleased with him) that once a Bedouin came to Masjid Nabawi while the Prophet Muhammad (ﷺ) was present there. He began to supplicate: "O Allah! Have mercy on me and on Muhammad (ﷺ), and do not include anyone else with us in it." The Prophet Muhammad (ﷺ) smiled, turned towards him, and said, "You have confined the vast mercy of Allah." Shortly after, that Bedouin began to urinate in the mosque. The Prophet Muhammad (ﷺ) stood up, went to him, and said, "These mosques are made for the remembrance of Allah and for prayer; urine is not to be passed in them." Then the Prophet Muhammad (ﷺ) called for a bucket of water and poured it over the urine. After this, when the Bedouin understood, he used to say, "May my parents be sacrificed for the Prophet Muhammad (ﷺ); he came to me standing, he did not abuse me, did not scold me, and did not beat me."
