The Prophet (ﷺ) and the people left the bedouin undisturbed till he finished urinating in the mosque

Sahih al-Bukhari · Book 4 · Hadith 219

حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ، قَالَ حَدَّثَنَا هَمَّامٌ، أَخْبَرَنَا إِسْحَاقُ، عَنْ أَنَسِ بْنِ مَالِكٍ، أَنَّ النَّبِيَّ صلى الله عليه وسلم رَأَى أَعْرَابِيًّا يَبُولُ فِي الْمَسْجِدِ فَقَالَ ‏"‏ دَعُوهُ ‏"‏‏.‏ حَتَّى إِذَا فَرَغَ دَعَا بِمَاءٍ فَصَبَّهُ عَلَيْهِ‏.‏

Narrated Anas bin Malik: The Prophet (ﷺ) saw a Bedouin making water in the mosque and told the people not to disturb him. When he finished, the Prophet (ﷺ) asked for some water and poured it over (the urine).
