جماع أبواب تطهير الثياب بالغسل من الأنجاسChapters on Purifying Clothes from Impurities
(229) بَابُ الزَّجْرِ عَنْ قَطْعِ الْبَوْلِ عَلَى الْبَائِلِ فِي الْمَسْجِدِ قَبْلَ الْفَرَاغِ مِنْهُChapter 229: Warning against interrupting someone urinating in the mosque before he finishes
Hadith Q296
وَالدَّلِيلُ عَلَى أَنَّ صَبَّ دَلْوٍ مِنْ مَاءٍ يُطَهِّرُ الْأَرْضَ، وَإِنْ لَمْ يَحْفِرْ مَوْضِعَ الْبَوْلِ فَيَنْقُلُ تُرَابَهُ مِنَ الْمَسْجِدِ عَلَى مَا زَعَمَ بَعْضُ الْعِرَاقِيِّينَ، إِذِ اللَّهُ عَزَّ وَجَلَّ أَنْعَمَ عَلَى عِبَادِهِ الْمُؤْمِنِينَ بِأَنْ بَعَثَ فِيهِمْ نَبِيَّهُ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ مُيَسِّرًا لَا مُعَسِّرًا
And the explanation of the evidence that pouring a bucket of water makes the ground pure, even if the place of urine is dug up and thrown outside the mosque, as is the opinion of some Iraqis (that the soil should be thrown outside the mosque), whereas Allah the Exalted has bestowed favor and kindness upon His believing servants by sending His Prophet (peace be upon him) as one who brings ease, not hardship.
