(20) بَاب تَزْوِيجِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ خَدِيجَةَ وَفَضْلِهَا رَضِيَ اللَّهُ عَنْهَا
Narrated Isma`il:
I asked `Abdullah bin Abi `Aufa, "Did the Prophet (ﷺ) 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."
