Fussilat 41:38

Fa-ini istakbaroo fallatheenaAAinda rabbika yusabbihoona lahu billayli wannahariwahum la yas-amoon

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.

Still, if they show arrogance, then those who are with your Lord proclaim His purity night and day, and they do not get weary.
