The prohibition of urinating into standing water
Sahih Muslim
وَحَدَّثَنَا مُحَمَّدُ بْنُ رَافِعٍ، حَدَّثَنَا عَبْدُ الرَّزَّاقِ، حَدَّثَنَا مَعْمَرٌ، عَنْ هَمَّامِ بْنِ مُنَبِّهٍ، قَالَ هَذَا مَا حَدَّثَنَا أَبُو هُرَيْرَةَ، عَنْ مُحَمَّدٍ، رَسُولِ اللَّهِ صلى الله عليه وسلم . فَذَكَرَ أَحَادِيثَ مِنْهَا وَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " لاَ تَبُلْ فِي الْمَاءِ الدَّائِمِ الَّذِي لاَ يَجْرِي ثُمَّ تَغْتَسِلُ مِنْهُ " .
Hammam b. Munabbih said: Of the ahadith narrated to us by Abfi Huraira from Muhammad the Messenger of Allah (ﷺ) one is this: The Messenger or Allah (ﷺ) said: You should not urinate in standing water, that is not flowing, then wash in it.
