حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا سُفْيَانُ بْنُ عُيَيْنَةَ، عَنِ الزُّهْرِيِّ، عَنْ سَعِيدِ بْنِ الْمُسَيَّبِ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ ‏"‏ الْفِطْرَةُ خَمْسٌ - أَوْ خَمْسٌ مِنَ الْفِطْرَةِ - الْخِتَانُ وَالاِسْتِحْدَادُ وَتَقْلِيمُ الأَظْفَارِ وَنَتْفُ الإِبِطِ وَقَصُّ الشَّارِبِ ‏"‏ ‏.‏

It was narrated that Anas bin Malik said

"We were given a time limit with regard to trimming the mustache, shaving the pubic hairs, plucking the armpit hairs and clipping the nails. We were not to leave that for more than forty days."
