Sahih al-Bukhari 7497
Narrated Abu Huraira:
The Prophet (ﷺ) said that Gabriel said, "Here is Khadija coming to you with a dish of food or a tumbler 
containing something to drink. Convey to her a greeting from her Lord (Allah) and give her the glad 
tidings that she will have a palace in Paradise built of Qasab wherein there will be neither any noise 
nor any fatigue (trouble)." (See Hadith No. 168, Vol. 5)
حَدَّثَنَا زُهَيْرُ بْنُ حَرْبٍ، حَدَّثَنَا ابْنُ فُضَيْلٍ، عَنْ عُمَارَةَ، عَنْ أَبِي زُرْعَةَ، عَنْ أَبِي هُرَيْرَةَ، فَقَالَ ‏
"‏ هَذِهِ خَدِيجَةُ أَتَتْكَ بِإِنَاءٍ فِيهِ طَعَامٌ أَوْ إِنَاءٍ فِيهِ شَرَابٌ فَأَقْرِئْهَا مِنْ رَبِّهَا السَّلاَمَ وَبَشِّرْهَا بِبَيْتٍ مِنْ قَصَبٍ لاَ صَخَبَ فِيهِ وَلاَ نَصَبَ ‏"‏‏.‏
