Narrated 'Aisha:

I never felt so jealous of any wife of Allah's Apostle as I did of Khadija because Allah's Apostle used to remember and praise her too often and because it was revealed to Allah's Apostle that he should give her (Khadija) the glad tidings of her having a palace of Qasab in Paradise .

حَدَّثَنِي أَحْمَدُ بْنُ أَبِي رَجَاءٍ، حَدَّثَنَا النَّضْرُ، عَنْ هِشَامٍ، قَالَ أَخْبَرَنِي أَبِي، عَنْ عَائِشَةَ، أَنَّهَا قَالَتْ مَا غِرْتُ عَلَى امْرَأَةٍ لِرَسُولِ اللَّهِ ﷺ كَمَا غِرْتُ عَلَى خَدِيجَةَ، لِكَثْرَةِ ذِكْرِ رَسُولِ اللَّهِ ﷺ إِيَّاهَا وَثَنَائِهِ عَلَيْهَا، وَقَدْ أُوحِيَ إِلَى رَسُولِ اللَّهِ ﷺ أَنْ يُبَشِّرَهَا بِبَيْتٍ لَهَا فِي الْجَنَّةِ مِنْ قَصَبٍ.
