Sunan an-Nasa'i 53
سنن النسائي#53SahihIt was narrated from Anas that a Bedouin urinated in the Masjid, and some of the people went after him, but the Messenger of Allah (ﷺ) said:"Leave him and do not restrain him." When he had finished he called for a bucket (of water) and poured it over it. [1] Abu 'Abdur-Rahman (An-Nasa'i) said: "Meaning: 'Do not interrupt him.'" [1]The author will cite this narration again in No. 330 as a possible proof for setting the minimum, since it mentions "a bucket" as if this is the minium amount required
