Urinating in stagnant water

باب الْبَوْلِ فِي الْمَاءِ الدَّائِمِ

Sahih al-Bukhari 239
وَبِإِسْنَادِهِ قَالَ ‏ ‏‏.‏
"‏ لاَ يَبُولَنَّ أَحَدُكُمْ فِي الْمَاءِ الدَّائِمِ الَّذِي لاَ يَجْرِي، ثُمَّ يَغْتَسِلُ فِيهِ ‏"
The same narrator said that the Prophet (ﷺ) had said:

"You should not pass urine in stagnant water which is not flowing then (you may need to) wash in it."
