Volume 7, Book 62, Number 156:
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 .
