وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ نَافِعٍ، عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ، عَنْ حَفْصَةَ أُمِّ الْمُؤْمِنِينَ، أَنَّهَا قَالَتْ لِرَسُولِ اللَّهِ صلى الله عليه وسلم مَا شَأْنُ النَّاسِ حَلُّوا وَلَمْ تَحْلِلْ أَنْتَ مِنْ عُمْرَتِكَ فَقَالَ ‏"‏ إِنِّي لَبَّدْتُ رَأْسِي وَقَلَّدْتُ هَدْيِي فَلاَ أَحِلُّ حَتَّى أَنْحَرَ ‏"‏ ‏.‏
