Compiled by Imam Muslim ibn al-Hajjaj
وَحَدَّثَنِي مُحَمَّدُ بْنُ حَاتِمٍ، حَدَّثَنَا بَهْزٌ، حَدَّثَنَا وُهَيْبٌ، حَدَّثَنَا عَبْدُ اللَّهِ بْنُ طَاوُسٍ، عَنْ أَبِيهِ، عَنْ أَبِي هُرَيْرَةَ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " حَقٌّ لِلَّهِ عَلَى كُلِّ مُسْلِمٍ أَنْ يَغْتَسِلَ فِي كُلِّ سَبْعَةِ أَيَّامٍ يَغْسِلُ رَأْسَهُ وَجَسَدَهُ " .
Abu Huraira reported that the Messenger of Allah (ﷺ) said. it is the right of Allah upon every Muslim that he should take a bath (at least) on one day (Friday) during the seven days (of the week) and he should wash his head and body.
