Narrated 'Amra:

I heard 'Aisha saying, "We set out (from Medina) along with Allah's Apostle five days before the end of Dhul-Qa'da with the intention of performing Hajj only. When we approached Mecca, Allah's Apostle ordered those who had no Hadi along with them to finish the lhram after performing Tawaf of the Ka'ba, (Safa and Marwa). 'Aisha added, "Beef was brought to us on the Day of Nahr and I said, 'What is this?' Somebody said, 'The Prophet has slaughtered (cows) on behalf of his wives.' "

حَدَّثَنَا خَالِدُ بْنُ مَخْلَدٍ، حَدَّثَنَا سُلَيْمَانُ، قَالَ حَدَّثَنِي يَحْيَى، قَالَ حَدَّثَتْنِي عَمْرَةُ، قَالَتْ سَمِعْتُ عَائِشَةَ ـ رضى الله عنها ـ تَقُولُ خَرَجْنَا مَعَ رَسُولِ اللَّهِ ﷺ لِخَمْسٍ بَقِينَ مِنْ ذِي الْقَعْدَةِ، وَلاَ نَرَى إِلاَّ الْحَجَّ، حَتَّى إِذَا دَنَوْنَا مِنْ مَكَّةَ أَمَرَ رَسُولُ اللَّهِ ﷺ مَنْ لَمْ يَكُنْ مَعَهُ هَدْىٌ إِذَا طَافَ بِالْبَيْتِ ثُمَّ يَحِلُّ. قَالَتْ عَائِشَةُ ـ رضى الله عنها ـ فَدُخِلَ عَلَيْنَا يَوْمَ النَّحْرِ بِلَحْمِ بَقَرٍ فَقُلْتُ مَا هَذَا فَقِيلَ ذَبَحَ النَّبِيُّ ﷺ عَنْ أَزْوَاجِهِ. قَالَ يَحْيَى فَذَكَرْتُ هَذَا الْحَدِيثَ لِلْقَاسِمِ. فَقَالَ أَتَتْكَ بِالْحَدِيثِ عَلَى وَجْهِهِ.
