[Machine] I met a man from the companions of the Prophet ﷺ who accompanied him just like Abu Hurayrah did. He did not teach me anything except for three words: the Messenger of Allah ﷺ said, "A man should not perform ghusl due to the favor of his wife, nor should she perform ghusl due to his favor. He should not urinate in the place of his ghusl, nor should he comb his hair every day."  

لَقِيتُ رَجُلًا مِنْ أَصْحَابِ النَّبِيِّ ﷺ صَحِبَهُ مِثْلَ مَا صَحِبَهُ أَبُو هُرَيْرَةَ فَمَا زَادَنِي عَلَى ثَلَاثِ كَلِمَاتٍ قَالَ رَسُولُ اللهِ ﷺ لَا يَغْتَسِلُ الرَّجُلُ مِنْ فَضْلِ امْرَأَتِهِ وَلَا تَغْتَسِلُ بِفَضْلِهِ وَلَا يَبُولُ فِي مُغْتَسَلِهِ وَلَا يَمْتَشِطُ فِي كُلِّ يَوْمٍ  

Humayd al-Himyari reported: I met a person (among the Companion of Prophet) who remained in the company of the Prophet ﷺfor four years as AbuHurayrah remained in his company. He reported: The Messenger of Allah ﷺ forbade that the female should wash with the water left over by the male, and that the male should wash with the left-over of the female. The version of Musaddad adds: "That they both take the handful of water together." (Using translation from Abū Dāʾūd 81)   

لَقِيتُ رَجُلًا قَدْ صَحِبَ النَّبِيَّ ﷺ أَرْبَعَ سِنِينَ كَمَا صَحِبَهُ أَبُو هُرَيْرَةَ أَرْبَعَ سِنِينَ قَالَ نَهَانَا رَسُولُ اللهِ ﷺ أَنْ يَمْتَشِطَ أَحَدُنَا كُلَّ يَوْمٍ وَأَنْ يَبُولَ فِي مُغْتَسَلِهِ وَأَنْ تَغْتَسِلَ الْمَرْأَةُ بِفَضْلِالرَّجُلِ وَأَنْ يَغْتَسِلَ الرَّجُلُ بِفَضْلِ الْمَرْأَةِ وَلْيَغْتَرِفُوا جَمِيعًا
