Narrated 'Aisha:

I never felt so jealous of any woman as I did of Khadija, though she had died three years before the Prophet married me, and that was because I heard him mentioning her too often, and because his Lord had ordered him to give her the glad tidings that she would have a palace in Paradise, made of Qasab and because he used to slaughter a sheep and distribute its meat among her friends.

حَدَّثَنَا عُبَيْدُ بْنُ إِسْمَاعِيلَ، حَدَّثَنَا أَبُو أُسَامَةَ، عَنْ هِشَامٍ، عَنْ أَبِيهِ، عَنْ عَائِشَةَ ـ رضى الله عنها ـ قَالَتْ مَا غِرْتُ عَلَى امْرَأَةٍ مَا غِرْتُ عَلَى خَدِيجَةَ، وَلَقَدْ هَلَكَتْ قَبْلَ أَنْ يَتَزَوَّجَنِي بِثَلاَثِ سِنِينَ، لِمَا كُنْتُ أَسْمَعُهُ يَذْكُرُهَا، وَلَقَدْ أَمَرَهُ رَبُّهُ أَنْ يُبَشِّرَهَا بِبَيْتٍ فِي الْجَنَّةِ مِنْ قَصَبٍ، وَإِنْ كَانَ لَيَذْبَحُ الشَّاةَ ثُمَّ يُهْدِي فِي خُلَّتِهَا مِنْهَا.
