وَعَنْ رَجُلٍ صَحِبَ اَلنَّبِيَّ - صلى الله عليه وسلم -قَالَ: "نَهَى رَسُولُ اَللَّهِ - صلى الله عليه وسلم -"أَنْ تَغْتَسِلَ اَلْمَرْأَةُ بِفَضْلِ اَلرَّجُلِ, أَوْ اَلرَّجُلُ بِفَضْلِ اَلْمَرْأَةِ, وَلْيَغْتَرِفَا جَمِيعًا" أَخْرَجَهُ أَبُو دَاوُدَ. وَالنَّسَائِيُّ, وَإِسْنَادُهُ صَحِيحٌ
A man who accompanied the prophet (ﷺ) narrated:
Allah’s Messenger (ﷺ) forbade a women to bathe with the water left over by a man and that a man should not bathe with the water left over by a woman (but instead) they should both take scoopfuls of the water together. .
