It was narrated that Abu Raihanah said:

"We heard that the Messenger of Allah [ﷺ] forbade filing (the teeth) and tattoos."

حَدَّثَنَا قُتَيْبَةُ، قَالَ حَدَّثَنَا اللَّيْثُ، عَنْ يَزِيدَ بْنِ أَبِي حَبِيبٍ، عَنْ أَبِي الْحُصَيْنِ الْحِمْيَرِيِّ، عَنْ أَبِي رَيْحَانَةَ، قَالَ بَلَغَنَا أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم نَهَى عَنِ الْوَشْرِ وَالْوَشْمِ ‏.‏
