“When the ten days (of Dhul-Hijjah) begin, and one of you wants to offer a sacrifice, let him not remove anything from his hair or skin.” (Using translation from Ibn Mājah 3149)
عَنِ النَّبِيِّ ﷺ قَالَ «إِذَا دَخَلَتِ الْعَشْرُ وَأَرَادَ أَحَدُكُمْ أَنْ يُضَحِّيَ فَلَا يَمَسَّ مِنْ شَعْرِهِ وَلَا أَظْفَارِهِ شَيْئًا»
