Bulugh al-Maram 102
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 .‏
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].
