Narrated `Aisha: I did not feel jealous of any woman as much as I did of Khadija because Allah's Apostle used to mention her very often. He married me after three years of her death, and his Lord (or Gabriel) ordered him to give her the good news of having a palace of Qasab in Paradise.

Narrated `Aisha: I did not feel jealous of any of the wives of the Prophet as much as I did of Khadija (although) she died before he married me, for I often heard him mentioning her, and Allah had told him to give her the good tidings that she would have a palace of Qasab (i.e. pipes of precious stones and pearls in Paradise), and whenever he slaughtered a sheep, he would send her women-friends a good share of it.

Narrated Isma`il: I asked `Abdullah bin Abi `Aufa, "Did the Prophet give glad tidings to Khadija?" He said, "Yes, of a palace of Qasab (in Paradise) where there will be neither any noise nor any fatigue."

Narrated 'Aisha: Once Hala bint Khuwailid, Khadija's sister, asked the permission of the Prophet to enter. On that, the Prophet remembered the way Khadija used to ask permission, and that upset him. He said, "O Allah! Hala!" So I became jealous and said, "What makes you remember an old woman amongst the old women of Quraish an old woman (with a teethless mouth) of red gums who died long ago, and in whose place Allah has given you somebody better than her?"

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 .

Narrated `Aisha: I never felt so jealous of any woman as I did of Khadija, though she had died three years before the Prophet married me, and that was because I heard him mentioning her too often, and because his Lord had ordered him to give her the glad tidings that she would have a palace in Paradise, made of Qasab and because he used to slaughter a sheep and distribute its meat among her friends.
