ٱلَّذِينَ يَحْمِلُونَ ٱلْعَرْشَ وَمَنْ حَوْلَهُۥ يُسَبِّحُونَ بِحَمْدِ رَبِّهِمْ وَيُؤْمِنُونَ بِهِۦ وَيَسْتَغْفِرُونَ لِلَّذِينَ ءَامَنُوا۟ رَبَّنَا وَسِعْتَ كُلَّ شَىْءٍۢ رَّحْمَةًۭ وَعِلْمًۭا فَٱغْفِرْ لِلَّذِينَ تَابُوا۟ وَٱتَّبَعُوا۟ سَبِيلَكَ وَقِهِمْ عَذَابَ ٱلْجَحِيمِ
Those who bear the Throne, and all who are round about it, hymn the praises of their Lord and believe in Him and ask forgiveness for those who believe (saying): Our Lord! Thou comprehendest all things in mercy and knowledge, therefor forgive those who repent and follow Thy way. Ward off from them the punishment of hell.
Surah Ghafir(40:7)
