كتاب مناقب الأنصار
Read the English translation first, with the original Arabic directly underneath.
Narrated `Aisha:
I did not feel jealous of any woman as much as I did of Khadija because Allah's Messenger (ﷺ) used to mention her very often. He married me after three years of her death, and his Lord (or Gabriel) ordered him to give her the good news of having a palace of Qasab in Paradise.
حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، حَدَّثَنَا حُمَيْدُ بْنُ عَبْدِ الرَّحْمَنِ، عَنْ هِشَامِ بْنِ عُرْوَةَ، عَنْ أَبِيهِ، عَنْ عَائِشَةَ ـ رضى الله عنها ـ قَالَتْ مَا غِرْتُ عَلَى امْرَأَةٍ مَا غِرْتُ عَلَى خَدِيجَةَ، مِنْ كَثْرَةِ ذِكْرِ رَسُولِ اللَّهِ صلى الله عليه وسلم إِيَّاهَا. قَالَتْ وَتَزَوَّجَنِي بَعْدَهَا بِثَلاَثِ سِنِينَ، وَأَمَرَهُ رَبُّهُ عَزَّ وَجَلَّ أَوْ جِبْرِيلُ ـ عَلَيْهِ السَّلاَمُ ـ أَنْ يُبَشِّرَهَا بِبَيْتٍ فِي الْجَنَّةِ مِنْ قَصَبٍ.
