Those angels who carry the Throne of Allah I make this dua for the Muminin.

Dua #2.
رَبَّنَا وَأَدْخِلْهُمْ جَنَّاتِ عَدْنٍ الَّتِي وَعَدتَّهُم وَمَن صَلَحَ مِنْ آبَائِهِمْ وَأَزْوَاجِهِمْ وَذُرِّيَّاتِهِمْ إِنَّكَ أَنتَ الْعَزِيزُ الْحَكِيمُ وَقِهِمُ السَّيِّئَاتِ وَمَن تَقِ السَّيِّئَاتِ يَوْمَئِذٍ فَقَدْ رَحِمْتَهُ وَذَلِكَ هُوَ الْفَوْزُ الْعَظِيمُ
غافر :8-9
Rabbana wa adhkhilhum Jannati 'adninil-lati wa'attahum wa man salaha min aba'ihim wa azwajihim wa dhuriyyatihim innaka antal 'Azizul-Hakim, waqihimus sayyi'at wa man taqis-sayyi'ati yawma'idhin faqad rahimatahu wa dhalika huwal fawzul-'Adheem
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. 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. - 40:8-9
This is also the dua of the angels for the believers.
Saeed bin Jubair (R.A.) narrates: When a person will enter Jannah, he will enquire regarding the abode of his father / brother and son. It will be said to him: “They did not reach your status as far as good deeds are concerned.” The person will reply, “The good deeds I used to do were for myself as well as for them”. Hence they will be joined with him. Thereafter Saeed (R.A.) recited the above ayah.
