Surah Fussilat — Ayah 38 (41:38)
فَإِنِ ٱسۡتَكۡبَرُواْ فَٱلَّذِينَ عِندَ رَبِّكَ يُسَبِّحُونَ لَهُۥ بِٱلَّيۡلِ وَٱلنَّهَارِ وَهُمۡ لَا يَسۡـَٔمُونَ۩ ٣٨
English translation (Saheeh International)
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.
Brief commentary
So if they show arrogance, turning away, not prostating to Allah the Creator, the angels that are with Allah glorify and praise Him (may He be glorified) throughout the day and night anyway, and they do not become bored of worshipping Him.
