Sahih al-Bukhari, Hadith 5229 ⓘ
Narrated `Aisha: I never felt so jealous of any wife of Allah's Messenger as I did of Khadija because Allah's Messenger used to remember and praise her too often and because it was revealed to Allah's Messenger 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 صلى الله عليه وسلم كَمَا غِرْتُ عَلَى خَدِيجَةَ، لِكَثْرَةِ ذِكْرِ رَسُولِ اللَّهِ صلى الله عليه وسلم إِيَّاهَا وَثَنَائِهِ عَلَيْهَا، وَقَدْ أُوحِيَ إِلَى رَسُولِ اللَّهِ صلى الله عليه وسلم أَنْ يُبَشِّرَهَا بِبَيْتٍ لَهَا فِي الْجَنَّةِ مِنْ قَصَبٍ.
