وَلِلْبُخَارِيِّ: «لَا يَبُولَنَّ أَحَدُكُمْ فِي اَلْمَاءِ اَلدَّائِمِ اَلَّذِي لَا يَجْرِي، ثُمَّ يَغْتَسِلُ فِيهِ». وَلِمُسْلِمٍ: «مِنْهُ». وَلِأَبِي دَاوُدَ: «وَلَا يَغْتَسِلُ فِيهِ مِنْ اَلْجَنَابَةِ»
“None of you should urinate in stagnant water that is not flowing, and then take bath in it”. A version of Muslim has the words “from it (i.e. the water)”. A version of Abu Daud has: “One should not take bath in it from sexual impurity”.
