Sunan Ibn Majah, Volume 4, Book 25, Hadith 3046 (DarusSalam) ⓘ

It was narrated from Ibn ‘Umar that Hafsah, the wife of the Prophet, said: “I said: ‘O Messenger of Allah, what is the matter with people who have exited Ihram when you have not exited your Ihram?’ He said: ‘I have applied something to my head to keep my hair together, and I have garlanded my sacrificial animal, so I will not exit Ihram until I have offered my sacrifice.’”

حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا أَبُو أُسَامَةَ، عَنْ عُبَيْدِ اللَّهِ بْنِ عُمَرَ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، أَنَّ حَفْصَةَ، زَوْجَ النَّبِيِّ ـ صلى الله عليه وسلم ـ قَالَتْ قُلْتُ يَا رَسُولَ اللَّهِ مَا شَأْنُ النَّاسِ حَلُّوا وَلَمْ تَحِلَّ أَنْتَ مِنْ عُمْرَتِكَ قَالَ ‏ "‏ إِنِّي لَبَّدْتُ رَأْسِي وَقَلَّدْتُ هَدْيِي فَلاَ أَحِلُّ حَتَّى أَنْحَرَ ‏" ‏ ‏.‏
