Divine remembrance (dhikr) and glorification (tasbīḥ)

فِى بُيُوتٍ أَذِنَ ٱللَّهُ أَن تُرْفَعَ وَيُذْكَرَ فِيهَا ٱسْمُهُۥ يُسَبِّحُ لَهُۥ فِيهَا بِٱلْغُدُوِّ وَٱلْـَٔاصَالِ

[Such niches are] in houses [i.e., mosques] which Allāh has ordered to be raised and that His name be mentioned [i.e., praised] therein; exalting Him within them in the morning and the evenings
