باب بَيَانِ وُجُوهِ الإِحْرَامِ وَأَنَّهُ يَجُوزُ إِفْرَادُ الْحَجِّ وَالتَّمَتُّعِ وَالْقِرَانِ وَجَوَازِ إِدْخَالِ الْحَجِّ عَلَى الْعُمْرَةِ وَمَتَى يَحِلُّ الْقَارِنُ مِنْ نُسُكِهِ
Sahih Muslim 1211 p

'Umra reported:

I heard A'isha (Allah be pleased with her) as saying: We went out with the Messenger of Allah (ﷺ) five days before the end of Dhi Qa'dah, and we did see but that he intended to perform Hajj (only), but as we came near Mecca the Messenger of Allah (ﷺ) commanded that he who did not have the sacrificial animal with him should put off Ihram after circumambulating the House and running between al-Safa and aI-Marwa (and thus convert his Ihram from that of Hajj to 'Umra). 'A'isha (Allah be pleased with her) said: The flesh of cow was sent to us on the Day of Sacrifice (10th of Dhu'I-Hijja). I said. What is this? It was said: The Messenger of Allah (ﷺ) sacrificed (the cow) on behalf of his wives. Yahya said: I made a mention of this hadith (what has been stated by Umra) to Qasim b. Muhammad, whereupon be said: By Allah, she has rightly narrated it to you.
وَحَدَّثَنَا عَبْدُ اللَّهِ بْنُ مَسْلَمَةَ بْنِ قَعْنَبٍ، حَدَّثَنَا سُلَيْمَانُ، - يَعْنِي ابْنَ بِلاَلٍ - عَنْ يَحْيَى، - وَهُوَ ابْنُ سَعِيدٍ - عَنْ عَمْرَةَ، قَالَتْ سَمِعْتُ عَائِشَةَ، - رضى الله عنها - تَقُولُ خَرَجْنَا مَعَ رَسُولِ اللَّهِ صلى الله عليه وسلم لِخَمْسٍ بَقِينَ مِنْ ذِي الْقَعْدَةِ وَلاَ نُرَى إِلاَّ أَنَّهُ الْحَجُّ حَتَّى إِذَا دَنَوْنَا مِنْ مَكَّةَ أَمَرَ رَسُولُ اللَّهِ صلى الله عليه وسلم مَنْ لَمْ يَكُنْ مَعَهُ هَدْىٌ إِذَا طَافَ بِالْبَيْتِ وَبَيْنَ الصَّفَا وَالْمَرْوَةِ أَنْ يَحِلَّ ‏.‏ قَالَتْ عَائِشَةُ رضى الله عنها فَدُخِلَ عَلَيْنَا يَوْمَ النَّحْرِ بِلَحْمِ بَقَرٍ فَقُلْتُ مَا هَذَا فَقِيِلَ ذَبَحَ رَسُولُ اللَّهِ صلى الله عليه وسلم عَنْ أَزْوَاجِهِ ‏.‏ قَالَ يَحْيَى فَذَكَرْتُ هَذَا الْحَدِيثَ لِلْقَاسِمِ بْنِ مُحَمَّدٍ فَقَالَ أَتَتْكَ وَاللَّهِ بِالْحَدِيثِ عَلَى وَجْهِهِ ‏.‏
