Sahih Muslim · Book 2: The Book of Purification · Cleaning oneself with water after defecating
Anas b. Malik reported:
وَ حَدَّثَنِي زُهَيْرُ بْنُ حَرْبٍ ، وَأَبُو كُرَيْبٍ - وَاللَّفْظُ لِزُهَيْرٍ - حَدَّثَنَا إِسْمَاعِيلُ، - يَعْنِي ابْنَ عُلَيَّةَ - حَدَّثَنِي رَوْحُ بْنُ الْقَاسِمِ ، عَنْ عَطَاءِ بْنِ أَبِي مَيْمُونَةَ ، عَنْ أَنَسِ بْنِ مَالِكٍ ، قَالَ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم يَتَبَرَّزُ لِحَاجَتِهِ فَآتِيهِ بِالْمَاءِ فَيَتَغَسَّلُ بِهِ .
The Messenger of Allah (ﷺ) went to a far-off place in the desert (hidden from the sight of human beings) for relieving himself. Then I brought water for him and he cleansed himself.
