Sahih Muslim Book - 44, Hadith - 6277

حَدَّثَنَا أَبُو كُرَيْبٍ مُحَمَّدُ بْنُ الْعَلاَءِ ، حَدَّثَنَا أَبُو أُسَامَةَ ، حَدَّثَنَا هِشَامٌ ، عَنْ أَبِيهِ ، عَنْ عَائِشَةَ ، قَالَتْ : مَا غِرْتُ عَلَى امْرَأَةٍ مَا غِرْتُ عَلَى خَدِيجَةَ وَلَقَدْ هَلَكَتْ قَبْلَ أَنْ يَتَزَوَّجَنِي بِثَلاَثِ سِنِينَ ، لِمَا كُنْتُ أَسْمَعُهُ يَذْكُرُهَا , وَلَقَدْ أَمَرَهُ رَبُّهُ عَزَّ وَجَلَّ أَنْ يُبَشِّرَهَا بِبَيْتٍ مِنْ قَصَبٍ فِي الْجَنَّةِ ، وَإِنْ كَانَ لَيَذْبَحُ الشَّاةَ ، ثُمَّ يُهْدِيهَا إِلَى خَلاَئِلِهَا.

It was narrated that 'Aishah said: "I never felt jealous of any woman as I did of Khadijah, although she died three years before he (s.a.w) married me. I used to hear him mention her, and his Lord told him to give her the glad tidings of a house of pearls in Paradise, and he used to slaughter a sheep and gift it to her friends."
