The Book of Purification
The Manners of Answering the Call of Nature
وَعَنْ أَبِي هُرَيْرَةَ - رضى الله عنه - { أَنَّ رَسُولَ اَللَّهِ - صلى الله عليه وسلم -نَهَى "أَنْ يُسْتَنْجَى بِعَظْمٍ, أَوْ رَوْثٍ" وَقَالَ: "إِنَّهُمَا لَا يُطَهِّرَانِ" } رَوَاهُ اَلدَّارَقُطْنِيُّ وَصَحَّحَه ُ [1] .
Narrated Abu Huraira (rad): Allah’s Messenger (ﷺ) forbade us to use a bone or dung for cleaning and said, “These two things do not purify”. [Reported by Ad-Daraqutni who graded it Sahih].
