'Abdullah b. Mughaffal reported God's messenger as saying, “No one must pass water where he bathes and then wash in it or perform ablution in it, for all evil promptings come from it.” Abu Dawud transmitted it, as did Tirmidhi and Nasa’i, but they did not mention “then wash in it or perform ablution in it”.

وَعَنْ عَبْدِ اللَّهِ بْنِ مُغَفَّلٍ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «لَا يَبُولَنَّ أَحَدُكُمْ فِي مُسْتَحَمِّهِ ثُمَّ يَغْتَسِلُ فِيهِ أَوْ يَتَوَضَّأُ فِيهِ فَإِنَّ عَامَّةَ الْوَسْوَاسِ مِنْهُ» . رَوَاهُ أَبُو دَاوُدَ وَالتِّرْمِذِيُّ وَالنَّسَائِيُّ إِلَّا أَنَّهُمَا لم يذكرَا: «ثمَّ يغْتَسل فِيهِ أويتوضأ فِيهِ»
