Sahih Muslim 1229
Sahih Muslim · Book 15: The Book of Pilgrimage · The pilgrim performing Qiran should not exit Ihram except when the pilgrims performing Ifrad exit Ihram
Hafsa (Allah be pleased with her) said that Allah's Apostle (ﷺ) commanded his wives that they should put off Ihram during the year of Hajj (at-ul-Wada'). whereupon she (Hafsa) said:
وَحَدَّثَنَا ابْنُ أَبِي عُمَرَ ، حَدَّثَنَا هِشَامُ بْنُ سُلَيْمَانَ الْمَخْزُومِيُّ ، وَعَبْدُ الْمَجِيدِ ، عَنِ ابْنِ جُرَيْجٍ ، عَنْ نَافِعٍ ، عَنِ ابْنِ عُمَرَ ، قَالَ حَدَّثَتْنِي حَفْصَةُ ، - رضى الله عنها - أَنَّ النَّبِيَّ صلى الله عليه وسلم أَمَرَ أَزْوَاجَهُ أَنْ يَحْلِلْنَ عَامَ حَجَّةِ الْوَدَاعِ . قَالَتْ حَفْصَةُ فَقُلْتُ مَا يَمْنَعُكَ أَنْ تَحِلَّ قَالَ " إِنِّي لَبَّدْتُ رَأْسِي وَقَلَّدْتُ هَدْيِي فَلاَ أَحِلُّ حَتَّى أَنْحَرَ هَدْيِي " .
What hinders you that you have not put off Ihram? Thereupon he said: I have stuck my hair and driven my sacrificial animal along with men and it is not permissible to put off Ihram (under this condition until I have sacrificed the animal.
