Narrated `Aisha:

I did not feel jealous of any of the wives of the Prophet (ﷺ) as much as I did of Khadija (although) she died before he married me, for I often heard him mentioning her, and Allah had told him to give her the good tidings that she would have a palace of Qasab (i.e. pipes of precious stones and pearls in Paradise), and whenever he slaughtered a sheep, he would send her women-friends a good share of it.

حَدَّثَنَا سَعِيدُ بْنُ عُفَيْرٍ، حَدَّثَنَا اللَّيْثُ، قَالَ كَتَبَ إِلَىَّ هِشَامٌ عَنْ أَبِيهِ، عَنْ عَائِشَةَ ـ رضى الله عنها ـ قَالَتْ مَا غِرْتُ عَلَى امْرَأَةٍ لِلنَّبِيِّ صلى الله عليه وسلم مَا غِرْتُ عَلَى خَدِيجَةَ، هَلَكَتْ قَبْلَ أَنْ يَتَزَوَّجَنِي، لِمَا كُنْتُ أَسْمَعُهُ يَذْكُرُهَا، وَأَمَرَهُ اللَّهُ أَنْ يُبَشِّرَهَا بِبَيْتٍ مِنْ قَصَبٍ، وَإِنْ كَانَ لَيَذْبَحُ الشَّاةَ فَيُهْدِي فِي خَلاَئِلِهَا مِنْهَا مَا يَسَعُهُنَّ‏.‏
