Muwatta Malik, Book 20, Hadith 196 (USC-MSA) ⓘ
Yahya related to me from Malik from Nafi that Abdullah ibn Umar used to trim his beard and moustache when he shaved at the end of a hajj or umra.
وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ نَافِعٍ، أَنَّ عَبْدَ اللَّهِ بْنَ عُمَرَ، كَانَ إِذَا حَلَقَ فِي حَجٍّ أَوْ عُمْرَةٍ أَخَذَ مِنْ لِحْيَتِهِ وَشَارِبِهِ .
