A message passed to someone through him
Jibrīl saw her approaching with food and gave instructions.
هَذِهِ خَدِيجَةُ أَتَتْكَ بِإِنَاءٍ فِيهِ طَعَامٌ أَوْ إِنَاءٍ فِيهِ شَرَابٌ فَأَقْرِئْهَا مِنْ رَبِّهَا السَّلاَمَ وَبَشِّرْهَا بِبَيْتٍ مِنْ قَصَبٍ لاَ صَخَبَ فِيهِ وَلاَ نَصَبَ
Here is Khadijah coming to you with a dish of food. When she reaches you, give her greetings of peace from her Lord and from me, and give her the good news of a house in Paradise of hollowed pearl, in which there is no noise and no weariness.
A house with no noise in it, and no tiredness. Both were things she had spent years without.
The full narration
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)
