IBNHIBBAN 816:
from Abū Saʿīd —
[Machine] From the Messenger of Allahﷺ he said: "Allah, Glorious and Exalted, says: 'The people of the gathering today will be recognized as the people of honor.' So it was said: 'Who are the people of honor, O Messenger of Allah?' He said: 'The people who gather for remembrance of Allah in the mosques.'"

عن ابو سعيد —
عَنْ رَسُولِ اللَّهِ ﷺ قَالَ «يَقُولُ اللَّهُ جَلَّ وَعَلَا سَيَعْلَمُ أَهْلُ الْجَمْعِ الْيَوْمَ مَنْ أَهْلُ الْكَرَمِ» فَقِيلَ مَنْ أَهْلُ الْكَرَمِ يَا رَسُولَ اللَّهِ؟ قَالَ «أَهْلُ مَجَالِسِ الذِّكْرِ فِي الْمَسَاجِدِ»
