Chapter 49: The Description of the Prophet, may Allah Bless Him and Grant Him Peace - كتاب صفة النبى صلى الله عليه وسلم
وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ سَعِيدِ بْنِ أَبِي سَعِيدٍ الْمَقْبُرِيِّ، عَنْ أَبِيهِ، عَنْ أَبِي هُرَيْرَةَ، قَالَ خَمْسٌ مِنَ الْفِطْرَةِ تَقْلِيمُ الأَظَافِرِ وَقَصُّ الشَّارِبِ وَنَتْفُ الإِبْطِ وَحَلْقُ الْعَانَةِ وَالاِخْتِتَانُ .
Yahya related to me from Malik from Said ibn Abi Said al-Maqburi from his father that Abu Hurayra said, "There are five things from the fitra:
cutting the nails, trimming the moustache, removing the hair from the armpit, shaving the pubic region and circumcision."
