Istighfar of angels for the believers

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 sustain the Throne (of Allah) and those around it Sing Glory and Praise to their Lord; believe in Him; and implore Forgiveness for those who believe: "Our Lord! Thy Reach is over all things, in Mercy and Knowledge. Forgive, then, those who turn in Repentance, and follow Thy Path; and preserve them from the Penalty of the Blazing Fire!

رَبَّنَا وَأَدْخِلْهُمْ جَنَّٰتِ عَدْنٍ ٱلَّتِى وَعَدتَّهُمْ وَمَن صَلَحَ مِنْ ءَابَآئِهِمْ وَأَزْوَٰجِهِمْ وَذُرِّيَّٰتِهِمْ ۚ إِنَّكَ أَنتَ ٱلْعَزِيزُ ٱلْحَكِيمُ

"And grant, our Lord! that they enter the Gardens of Eternity, which Thou hast promised to them, and to the righteous among their fathers, their wives, and their posterity! For Thou art (He), the Exalted in Might, Full of Wisdom.

وَقِهِمُ ٱلسَّيِّـَٔاتِ ۚ وَمَن تَقِ ٱلسَّيِّـَٔاتِ يَوْمَئِذٍۢ فَقَدْ رَحِمْتَهُۥ ۚ وَذَٰلِكَ هُوَ ٱلْفَوْزُ ٱلْعَظِيمُ

"And preserve them from (all) ills; and any whom Thou dost preserve from ills that Day,- on them wilt Thou have bestowed Mercy indeed: and that will be truly (for them) the highest Achievement".

تَكَادُ ٱلسَّمَٰوَٰتُ يَتَفَطَّرْنَ مِن فَوْقِهِنَّ ۚ وَٱلْمَلَٰٓئِكَةُ يُسَبِّحُونَ بِحَمْدِ رَبِّهِمْ وَيَسْتَغْفِرُونَ لِمَن فِى ٱلْأَرْضِ ۗ أَلَآ إِنَّ ٱللَّهَ هُوَ ٱلْغَفُورُ ٱلرَّحِيمُ

The heavens are almost rent asunder from above them (by Him Glory): and the angels celebrate the Praises of their Lord, and pray for forgiveness for (all) beings on earth: Behold! Verily Allah is He, the Oft-Forgiving, Most Merciful.
