"I met a man who accompanied the Prophet ﷺ as Abu Hurairah (may Allah be pleased with him), accompanied him for four years. He said: 'The Messenger of Allah ﷺ forbade any one of us to comb his hair each day,[1] or to urinate in the place where he performs Ghusl, or for a man to perform Ghusl using the leftover water of a women, or a woman to perform Ghusl using the leftover water of a man - they should scoop it out together.'" [1] It is said this is to prevent him from making his physical appearance his main aim.  

لَقِيتُ رَجُلاً صَحِبَ النَّبِيَّ ﷺ كَمَا صَحِبَهُ أَبُو هُرَيْرَةَ ؓ أَرْبَعَ سِنِينَ قَالَ نَهَى رَسُولُ اللَّهِ ﷺ أَنْ يَمْتَشِطَ أَحَدُنَا كُلَّ يَوْمٍ أَوْ يَبُولَ فِي مُغْتَسَلِهِ أَوْ يَغْتَسِلَ الرَّجُلُ بِفَضْلِ الْمَرْأَةِ وَالْمَرْأَةُ بِفَضْلِ الرَّجُلِ وَلْيَغْتَرِفَا جَمِيعًا  

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."  

لَقِيتُ رَجُلاً صَحِبَ النَّبِيَّ ﷺ أَرْبَعَ سِنِينَ كَمَا صَحِبَهُ أَبُو هُرَيْرَةَ قَالَ نَهَى رَسُولُ اللَّهِ ﷺ أَنْ تَغْتَسِلَ الْمَرْأَةُ بِفَضْلِ الرَّجُلِ أَوْ يَغْتَسِلَ الرَّجُلُ بِفَضْلِ الْمَرْأَةِ زَادَ مُسَدَّدٌ وَلْيَغْتَرِفَا جَمِيعًا

لَقِيتُ رَجُلًا صَحِبَ النَّبِيَّ ﷺ كَمَا صَحِبَهُ أَبُو هُرَيْرَةَ أَرْبَعَ سِنِينَ قَالَ نَهَانَا رَسُولُ اللهِ ﷺ أَنْ يَتَمَشَّطَ أَحَدُنَا كُلَّ يَوْمٍ أَوْ يَبُولَ فِي مُغْتَسَلِهِ أَوْ تَغْتَسِلَ الْمَرْأَةُ بِفَضْلِ الرَّجُلِ أَوْ يَغْتَسِلَ الرَّجُلُ بِفَضْلِ الْمَرْأَةِ وَلْيَغْتَرِفَا جَمِيعًا

"عَنْ حُمَيْدِ بْنِ عَبْدِ الرَّحْمَنِ قَالَ: لَقِيتُ رَجُلًا صَحِبَ رَسُولَ اللهِ ﷺ أَرْبَعَ سِنِينَ كَمَا صَحِبَهُ أَبُو هُرَيْرَةَ قَالَ: نَهَانَا رَسُولُ اللهِ ﷺ أَنْ يَتَمَشَّطَ أَحَدُنَا

كُلَّ يَوْمٍ، أَو أَنْ يَبُولَ فِي مُغْتَسَلِهِ، أَوْ أَنْ يَغْتَسِلَ الرَّجُلُ بِفَضْلِ الْمَرأَةِ، أَو الْمَرأَةُ بَفَضْلِ الرَّجُلِ وَقَالَ: لِيَفْتَرِقا جَمِيعًا".
