Fussilat 41:38

فَإِنِ ٱسْتَكْبَرُوا۟ فَٱلَّذِينَ عِندَ رَبِّكَ يُسَبِّحُونَ لَهُۥ بِٱلَّيْلِ وَٱلنَّهَارِ وَهُمْ لَا يَسْـَٔمُونَ ۩

Fa-ini is'takbarū fa-alladhīna ʿinda rabbika yusabbiḥūna lahu bi-al-layli wal-nahāri wahum lā yasamūna

But if they are arrogant - then those who are near your Lord [i.e., the angels] exalt Him by night and by day, and they do not become weary.
