Angels miss and support the frequenters of the mosques while they're absent
AHMAD 9424:
from Abū Hurayrah —
from the Prophet ﷺ who said, "Mosques have pillars (those who frequent them) with whom the angels sit. If they are absent, the angels miss their presence. If they are sick, the angels visit them. If they are in need, the angels support them.”
أحمد ٩٤٢٤:
عن ابو هريره —
عَنِ النَّبِيِّ ﷺ قَالَ: «إِنَّ لِلْمَسَاجِدِ أَوْتَادًا الْمَلَائِكَةُ جُلَسَاؤُهُمْ: إِنْ غَابُوا يَفْتَقِدُونَهُمْ، وَإِنْ مَرِضُوا عَادُوهُمْ، وَإِنْ كَانُوا فِي حَاجَةٍ أَعَانُوهُمْ.»
