"The Messenger of Allah forbade men to perform ablution with the water left over by a woman, and women to perform ablution with water left over by a man, however both (spouses) may start to perform their ablutions at the same time."

ابن ماجة:٣٧٤حَدَّثَنَا مُحَمَّدُ بْنُ يَحْيَى حَدَّثَنَا الْمُعَلَّى بْنُ أَسَدٍ حَدَّثَنَا عَبْدُ الْعَزِيزِ بْنُ الْمُخْتَارِ حَدَّثَنَا عَاصِمٌ الأَحْوَلُ عَنْ عَبْدِ اللَّهِ بْنِ سَرْجِسَ قَالَ

نَهَى رَسُولُ اللَّهِ ﷺ أَنْ يَغْتَسِلَ الرَّجُلُ بِفَضْلِ وَضُوءِ الْمَرْأَةِ وَالْمَرْأَةُ بِفَضْلِ الرَّجُلِ وَلَكِنْ يَشْرَعَانِ جَمِيعًا قَالَ أَبُو عَبْدِ اللَّهِ بْنُ مَاجَهْ الصَّحِيحُ هُوَ الأَوَّلُ وَالثَّانِي وَهَمٌ قَالَ أَبُو الْحَسَنِ بْنُ سَلَمَةَ حَدَّثَنَا أَبُو حَاتِمٍ وَأَبُو عُثْمَانَ الْبُخَارِيُّ قَالاَ حَدَّثَنَا الْمُعَلَّى بْنُ أَسَدٍ نَحْوَهُ
