1. Rasulullah (Sallallahu Alaihi Wasallam) has mentioned in the mubaarak Hadith that one should comb his hair every second day. The reason for this teaching is so that a man does not make his purpose in life beautifying himself. However, it is also recorded in the Hadith that the one whose hair has grown long and he is in need of combing it everyday, then in order to keep himself tidy and look presentable before people, he may comb it everyday.
عن عبد الله بن مغفل قال : نهى رسول الله صلى الله عليه و سلم عن الترجل إلا غبا (ترمذي رقم 1756)
Hadhrat Abdullah bin Mughaffal (Radhiyallahu Anhu) reports: “Rasulullah (Sallallahu Alaihi Wasallam) discouraged (a male) combing the hair except on alternate days.”
عن أبي قتادة قال : كانت له جمة ضخمة فسأل النبي صلى الله عليه و سلم فأمره أن يحسن إليها وأن يترجل كل يوم (نسائي رقم 5237)
Hadhrat Abu Qataadah (Radhiyallahu Anhu) reports that he had thick, long hair. He asked Rasulullah (Sallallahu Alaihi Wasallam) regarding (combing) it. Rasulullah (Sallallahu Alaihi Wasallam) instructed him to look after it and to comb it everyday.”
