Muwatta Malik, Book 20, Hadith 899 (In-Book) ⓘ
Yahya related to me from Malik from Nafi from 'Abdullah ibn 'Umar that Umar ibn al-Khattab said, "Someone who puts plaits in his hair should shave his head, and do not plait your hair in such a way that it seems you have matted it."
حَدَّثَنِي يَحْيَى، عَنْ مَالِكٍ، عَنْ نَافِعٍ، عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ، أَنَّ عُمَرَ بْنَ الْخَطَّابِ، قَالَ مَنْ ضَفَرَ رَأْسَهُ فَلْيَحْلِقْ وَلاَ تَشَبَّهُوا بِالتَّلْبِيدِ .
