حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ، حَدَّثَنَا أَبُو دَاوُدَ، حَدَّثَنَا شُعْبَةُ، عَنْ عَاصِمٍ الأَحْوَلِ، عَنْ أَبِي حَاجِبٍ، عَنِ الْحَكَمِ بْنِ عَمْرٍو، أَنَّ رَسُولَ اللَّهِ ـ صلى الله عليه وسلم ـ نَهَى أَنْ يَتَوَضَّأَ الرَّجُلُ بِفَضْلِ وَضُوءِ الْمَرْأَةِ ‏.‏

It was narrated that 'Ali said

"The Prophet and his wife would take a bath from one vessel, but neither of them would have a bath with the leftover water of the other." (Daif)
