Sunan an-Nasai
أَخْبَرَنَا مُحَمَّدُ بْنُ حَاتِمٍ، قَالَ حَدَّثَنَا حِبَّانُ، قَالَ حَدَّثَنَا عَبْدُ اللَّهِ، عَنْ حَيْوَةَ بْنِ شُرَيْحٍ، قَالَ حَدَّثَنِي عَيَّاشُ بْنُ عَبَّاسٍ الْقِتْبَانِيُّ، عَنْ أَبِي الْحُصَيْنِ الْحِمْيَرِيِّ، أَنَّهُ كَانَ هُوَ وَصَاحِبٌ لَهُ يَلْزَمَانِ أَبَا رَيْحَانَةَ يَتَعَلَّمَانِ مِنْهُ خَيْرًا قَالَ فَحَضَرَ صَاحِبِي يَوْمًا فَأَخْبَرَنِي صَاحِبِي أَنَّهُ سَمِعَ أَبَا رَيْحَانَةَ يَقُولُ إِنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم حَرَّمَ الْوَشْرَ وَالْوَشْمَ وَالنَّتْفَ .
It was narrated from Abu Al-Husain Al-Himyari that : He and a companion of his used to stay with Abu Raihanah to learn good things from him. He said: "One day my companion came and told me that he heard Abu Raihanah say: 'The Messenger of Allah [SAW] forbade filing (the teeth), tattoos, and plucking hairs.'"
