عَنْ عَبْدِ اللَّهِ بْنِ مُغَفَّلٍ الْمُزَنِيِّ رَضِيَ اللَّهُ عَنْهُ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ نَهَى عَنِ التَّرَجُّلِ إِلَّا غِبًّا
Sayyiduna Abdullah bin Mughaffal Muzani (may Allah be pleased with him) narrates that the Noble Prophet (peace and blessings be upon him) forbade combing the hair without a break.
