CHAPTER: Trimming The Moustache.
Narrated Abu Hurairah: The Prophet صلی اللہ علیہ وسلم as saying: The inborn characteristics of man are five. Another version says: Five things are of the inborn characteristics of man: circumcision, shaving the pubes, plucking out hair under the armpit, paring the nails and clipping the moustaches.
Narrated Abdullah bin Umar: The Messenger of Allah صلی اللہ علیہ وسلم commanded to clip the moustaches and grow the beard long.
Narrated Anas bin Malik: The Messenger of Allah صلی اللہ علیہ وسلم fixed forty days to shave the pubes, paring the nails, clipping the moustaches, and plucking the hair under the armpit. Abu Dawud said: Jafar bin Sulaiman transmitted it from Abu Imran on the authority of Anas. In this version he did not mention the Prophet صلی اللہ علیہ وسلم. He said: Forty days were fixed for us. This is a more correct version.
Narrated Jabir: We used to grow beard long except during the Hajj or Umrah. Abu Dawud said: Istihdad means to shave the pubes.
