The obligation to wash away urine and other impurities if they result in the Masjid, and the ground may be purified with water with no need to scrub it

Anas reported:

A Bedouin urinated in the mosque. Some of the persons stood up (to reprimand him or to check him from doing so), but the Messenger of Allah (ﷺ) said: Leave him alone; don't interrupt him. He (the narrator) said: And when he had finished, he called for a bucket of water and poured it over.

وَحَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، حَدَّثَنَا حَمَّادٌ، - وَهُوَ ابْنُ زَيْدٍ - عَنْ ثَابِتٍ، عَنْ أَنَسٍ، أَنَّ أَعْرَابِيًّا، بَالَ فِي الْمَسْجِدِ فَقَامَ إِلَيْهِ بَعْضُ الْقَوْمِ فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏

‏ دَعُوهُ وَلاَ تُزْرِمُوهُ ‏

‏ ‏.‏ قَالَ فَلَمَّا فَرَغَ دَعَا بِدَلْوٍ مِنْ مَاءٍ فَصَبَّهُ عَلَيْهِ ‏.‏

Anas b. Malik narrated that a desert Arab (Bedouin) stood in a corner of the mosque and urinated there. The people (the Companions of the Prophet (ﷺ) who were present there) shouted, but the Messenger of Allah (ﷺ) said:

Leave him alone. When he had finished, the Messenger of Allah (ﷺ) ordered that a bucket (of water) should be brought and poured over it.

حَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، حَدَّثَنَا يَحْيَى بْنُ سَعِيدٍ الْقَطَّانُ، عَنْ يَحْيَى بْنِ سَعِيدٍ الأَنْصَارِيِّ، ح وَحَدَّثَنَا يَحْيَى بْنُ يَحْيَى، وَقُتَيْبَةُ بْنُ سَعِيدٍ، جَمِيعًا عَنِ الدَّرَاوَرْدِيِّ، - قَالَ يَحْيَى بْنُ يَحْيَى أَخْبَرَنَا عَبْدُ الْعَزِيزِ بْنُ مُحَمَّدٍ الْمَدَنِيُّ، - عَنْ يَحْيَى بْنِ سَعِيدٍ، أَنَّهُ سَمِعَ أَنَسَ بْنَ مَالِكٍ، يَذْكُرُ أَنَّ أَعْرَابِيًّا، قَامَ إِلَى نَاحِيَةٍ فِي الْمَسْجِدِ فَبَالَ فِيهَا فَصَاحَ بِهِ النَّاسُ فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏

‏ دَعُوهُ ‏

‏ ‏.‏ فَلَمَّا فَرَغَ أَمَرَ رَسُولُ اللَّهِ صلى الله عليه وسلم بِذَنُوبٍ فَصُبَّ عَلَى بَوْلِهِ ‏.‏

Anas b. Malik reported:

While we were in the mosque with Allah's Messenger (ﷺ), a desert Arab came and stood up and began to urinate in the mosque. The Companions of Allah's Messenger (ﷺ) said: Stop, stop, but the Messenger of Allah (ﷺ) said: Don't interrupt him; leave him alone. They left him alone, and when he finished urinating, Allah's Messenger (ﷺ) called him and said to him: These mosques are not the places meant for urine and filth, but are only for the remembrance of Allah, prayer and the recitation of the Qur'an, or Allah's Messenger (ﷺ) said something like that. He (the narrator) said that he (the Prophet) then gave orders to one of the people who brought a bucket of water and poured It over.

حَدَّثَنَا زُهَيْرُ بْنُ حَرْبٍ، حَدَّثَنَا عُمَرُ بْنُ يُونُسَ الْحَنَفِيُّ، حَدَّثَنَا عِكْرِمَةُ بْنُ عَمَّارٍ، حَدَّثَنَا إِسْحَاقُ بْنُ أَبِي طَلْحَةَ، حَدَّثَنِي أَنَسُ بْنُ مَالِكٍ، - وَهُوَ عَمُّ إِسْحَاقَ - قَالَ بَيْنَمَا نَحْنُ فِي الْمَسْجِدِ مَعَ رَسُولِ اللَّهِ صلى الله عليه وسلم إِذْ جَاءَ أَعْرَابِيٌّ فَقَامَ يَبُولُ فِي الْمَسْجِدِ فَقَالَ أَصْحَابُ رَسُولِ اللَّهِ صلى الله عليه وسلم مَهْ مَهْ ‏.‏ قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ لاَ تُزْرِمُوهُ دَعُوهُ ‏"‏ ‏.‏ فَتَرَكُوهُ حَتَّى بَالَ ‏.‏ ثُمَّ إِنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم دَعَاهُ فَقَالَ لَهُ ‏"‏ إِنَّ هَذِهِ الْمَسَاجِدَ لاَ تَصْلُحُ لِشَىْءٍ مِنْ هَذَا الْبَوْلِ وَلاَ الْقَذَرِ إِنَّمَا هِيَ لِذِكْرِ اللَّهِ عَزَّ وَجَلَّ وَالصَّلاَةِ وَقِرَاءَةِ الْقُرْآنِ ‏"‏ ‏.‏ أَوْ كَمَا قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏.‏ قَالَ فَأَمَرَ رَجُلاً مِنَ الْقَوْمِ فَجَاءَ بِدَلْوٍ مِنْ مَاءٍ فَشَنَّهُ عَلَيْهِ ‏.‏
