حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا سُفْيَانُ، عَنِ الزُّهْرِيِّ، عَنْ سَعِيدٍ، عَنْ أَبِي هُرَيْرَةَ، يَبْلُغُ بِهِ النَّبِيَّ صلى الله عليه وسلم ‏"‏ الْفِطْرَةُ خَمْسٌ أَوْ خَمْسٌ مِنَ الْفِطْرَةِ الْخِتَانُ وَالاِسْتِحْدَادُ وَنَتْفُ الإِبْطِ وَتَقْلِيمُ الأَظْفَارِ وَقَصُّ الشَّارِبِ ‏"‏ ‏.‏

Narrated Anas bin Malik

The Messenger of Allah (ﷺ) fixed forty days to shave the pubes, paring the nails, clipping the moustaches, and plucking the hair under the armpit.

Abu Dawud said: Ja'far b. Sulaiman transmitted it from Abu 'Imran on the authority of Anas. In this version he did not mention the Prophet (ﷺ). He said: Forty days were fixed for us. This is a more correct version.
