(20) بَاب تَزْوِيجِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ خَدِيجَةَ وَفَضْلِهَا رَضِيَ اللَّهُ عَنْهَا
Narrated Abu Huraira:
Gabriel came to the Prophet (ﷺ) and said, "O Allah's Messenger (ﷺ)! This is Khadija coming to you with a dish having meat soup (or some food or drink). When she reaches you, greet her on behalf of her Lord (i.e. Allah) and on my behalf, and give her the glad tidings of having a Qasab palace in Paradise wherein there will be neither any noise nor any fatigue (trouble) . "
