Sahih al-Bukhari, Hadith 1725 ⓘ
Narrated Ibn `Umar: Hafsa said, "O Allah's Messenger! What is wrong with the people; they finished their Ihram after performing `Umra, but you have not finished it after your `Umra?" He replied, "I matted my hair and have garlanded my Hadi. So, I cannot finish my Ihram till I slaughter (my Hadi). "
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ يُوسُفَ، أَخْبَرَنَا مَالِكٌ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، عَنْ حَفْصَةَ ـ رضى الله عنهم ـ أَنَّهَا قَالَتْ يَا رَسُولَ اللَّهِ، مَا شَأْنُ النَّاسِ حَلُّوا بِعُمْرَةٍ وَلَمْ تَحْلِلْ أَنْتَ مِنْ عُمْرَتِكَ قَالَ " إِنِّي لَبَّدْتُ رَأْسِي، وَقَلَّدْتُ هَدْيِي، فَلاَ أَحِلُّ حَتَّى أَنْحَرَ " .
