Is it sufficient for one who is sexually impure to immerse himself in standing water?
حَدَّثَنَا أَحْمَدُ بْنُ عِيسَى، وَحَرْمَلَةُ بْنُ يَحْيَى الْمِصْرِيَّانِ، قَالاَ حَدَّثَنَا ابْنُ وَهْبٍ، عَنْ عَمْرِو بْنِ الْحَارِثِ، عَنْ بُكَيْرِ بْنِ عَبْدِ اللَّهِ بْنِ الأَشَجِّ، أَنَّ أَبَا السَّائِبِ، مَوْلَى هِشَامِ بْنِ زُهْرَةَ حَدَّثَهُ أَنَّهُ، سَمِعَ أَبَا هُرَيْرَةَ، يَقُولُ قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ " لاَ يَغْتَسِلْ أَحَدُكُمْ فِي الْمَاءِ الدَّائِمِ وَهُوَ جُنُبٌ " . فَقَالَ كَيْفَ يَفْعَلُ يَا أَبَا هُرَيْرَةَ فَقَالَ يَتَنَاوَلُهُ تَنَاوُلاً .
It was narrated from Bukair bin 'Abdullah bin Ashajj that: Abu Sa'ib, the freed slave of Hisham bin Zuhrah, told him that he heard Abu Hurairah say: "The Messenger of Allah (ﷺ) said: 'No one of you should bathe in standing water when he is sexually impure.'" He (Abu Sa'ib) said: "What should he do, O Abu Hurairah?" He said: "Let him take some out (and pour it over himself)."
