A bedouin entered the mosque while the Messenger of Allah (ﷺ) was sitting. He offered two rak'ahs of prayer, according to the version of Ibn 'Abdah. He then said: O Allah, have mercy on me and on Muhammad and do not have mercy on anyone along with us. The Prophet (ﷺ) said: You have narrowed down (a thing) that was broader. After a short while he passed a water in the corner of the mosque. The people rushed towards him. The Prophet (ﷺ) prevented them and said: You have been sent to facilitate and not create difficulties. Pour a bucket of water upon it.
Sunan Abi Dawud Book 1, Hadith 380
← Previous Hadith Al-Hasan reported on the authority of his mother that she was Umm Salamah pouring water on the urine of the male child until the age when he did not eat food. When he began to eat food, she would wash (his urine). And she would wash the urine of the female child.

Sunan Abi Dawud Book 1, Hadith 379 Next Hadith → A bedouin prayed with the Prophet (ﷺ). He then narrated the tradition (No 0380) about urinating of that bedouin.

This version adds: The Prophet (ﷺ) said: Remove the earth where he urinated and throw it away and pour water upon the place.

Abu Dawud said: This is a mursal tradition (i.e. the narrator quotes the Prophet (ﷺ) directly, although he did not see him). Ibn Ma'qil did not see the Prophet (ﷺ).
