Sunan an-Nasa'i 2682
It was narrated from 'Abdullah bin 'Umar that his sister, Hafsah, said;
"I said to the Prophet;'O Messenger of Allah! Why is it that the people have exited Ihram and you have not exited Ihram following your 'Umrah?'He said:
'I have matted my hair and garlanded my Hadi (sacrificial animal), so I will not exit Ihram until I exit Ihram after Hajj.'''
أَخْبَرَنَا عُبَيْدُ اللَّهِ بْنُ سَعِيدٍ، قَالَ حَدَّثَنَا يَحْيَى، عَنْ عُبَيْدِ اللَّهِ، قَالَ أَخْبَرَنِي نَافِعٌ، عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ، عَنْ أُخْتِهِ، حَفْصَةَ قَالَتْ قُلْتُ لِلنَّبِيِّ صلى الله عليه وسلم يَا رَسُولَ اللَّهِ مَا شَأْنُ النَّاسِ حَلُّوا وَلَمْ تَحِلَّ مِنْ عُمْرَتِكَ قَالَ ‏
"‏ إِنِّي لَبَّدْتُ رَأْسِي وَقَلَّدْتُ هَدْيِي فَلاَ أُحِلُّ حَتَّى أُحِلَّ مِنَ الْحَجِّ ‏"‏ ‏.‏
