The Prophet (ﷺ) used to say this dua after every compulsory prayer:

لَا إِلَهَ إِلَّا اللَّهُ وَحْدَهُ لَا شَرِيْكَ لَهُ، لَهُ الْمُلْكُ وَلَهُ الْحَمْدُ، وَهُوَ عَلَى كُلِّ شَيْءٍ قَدِيرٌ، اَللَّهُمَّ لَا مَانِعَ لِمَا أَعْطَيْتَ، وَلَا مُعْطِىَ لِمَا مَنَعْتَ، وَلَا يَنْفَعُ ذَا الْجَدِّ مِنْكَ الْجَدُّ

Laa ilaaha ill-Allahu wa'hdahu laa shareeka lahu, lahul-mulku wa lahul-'hamdu wa huwa ‛alaa kulli shay’in qadeer, Allaahumma laa maani‛a li maa a‛tayta, wa laa mu‛tiya li maa mana‛ta wa laa yanfa‛u dhal-jaddi minkal-jaddu

None has the right to be worshipped except Allah, alone, without partner, to Him belongs all sovereignty and praise and and He is Able to do all things. O Allah, none can prevent what You have willed to bestow and none can bestow what You have willed to prevent, and no wealth or majesty can benefit anyone, as from You is all wealth and majesty.
