The Quran

الَّذينَ يَحمِلونَ العَرشَ وَمَن حَولَهُ يُسَبِّحونَ بِحَمدِ رَبِّهِم وَيُؤمِنونَ بِهِ وَيَستَغفِرونَ لِلَّذينَ آمَنوا رَبَّنا وَسِعتَ كُلَّ شَيءٍ رَحمَةً وَعِلمًا فَاغفِر لِلَّذينَ تابوا وَاتَّبَعوا سَبيلَكَ وَقِهِم عَذابَ الجَحيمِ

Ali Unal

Those (angels) who bear the Supreme Throne (of God), and the others around it¹ glorify their Lord with His praise;² and they believe in Him (as the Unique Deity, Lord, and Sovereign of all creation), and ask for His forgiveness for those (among His creation) who believe, saying: “Our Lord! You embrace all things with mercy and knowledge (having perfect knowledge of every creature’s need, and answering that need with mercy), so forgive those who repent (of their sins) and follow Your way, and protect them from the punishment of the Blazing Flame.

On the nature and duties of angels, see sūrah 2: 30, note 31; on God’s Supreme Throne: sūrah 7: 54, note 13; sūrah 11: 7, note 2; sūrah 17: 42, note 19, and sūrah 69: 17, note 8. Bearing the Supreme Throne means, in one respect, carrying out the Divine orders issued from His absolute Sovereignty over the universe. As for those who are around the Supreme Throne mentioned in the verse, they must be the angels who have greater nearness to God in rank.
For glorifying God with His praise, see sūrah 35: 29, note 11. The verse suggests that those (angels) bearing God’s Supreme Throne carry out His orders in such perfection that they prove that God is absolutely above having any defects and partners and that He is One to Whom praise is absolutely due.
