What did the Prophet Muhammad (saw) give Khadija (peace be upon her) as the glad tidings of her having a palace of Qasab in Paradise?
 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 .
