أَخْبَرَنَا قُتَيْبَةُ، عَنْ مَالِكٍ، عَنِ الْمَقْبُرِيِّ، عَنْ أَبِي هُرَيْرَةَ، قَالَ خَمْسٌ مِنَ الْفِطْرَةِ تَقْلِيمُ الأَظْفَارِ وَقَصُّ الشَّارِبِ وَنَتْفُ الإِبْطِ وَحَلْقُ الْعَانَةِ وَالْخِتَانُ .
It was narrated that Abu Hurairah said: "Five things are of the Fitrah: Clipping the nails, trimming the mustache, plucking the armpit hairs, shaving the pubes, and circumcision." (Sahih Mawquf)
