(108) باب غَيْرَةِ النِّسَاءِ وَوَجْدِهِنَّ
Narrated `Aisha:
I never felt so jealous of any wife of Allah's Messenger (ﷺ) as I did of Khadija because Allah's Messenger (ﷺ) used to remember and praise her too often and because it was revealed to Allah's Messenger (ﷺ) that he should give her (Khadija) the glad tidings of her having a palace of Qasab in Paradise .
