Suhaib (RA) said: The Prophet (ﷺ) used to say this dua at the end of the prayer:

اَللَّهُمَّ أَصْلِحْ لِي دِيْنِيَ الَّذِي جَعَلْتَهُ عِصْمَةَ أَمْرِي، وَأَصْلِحْ لِي دُنْيَايَ الَّتِي جَعَلْتَ فِيهَا مَعَاشِيْ، اَللَّهُمَّ إِنِّي أَعُوْذُ بِرِضَاكَ مِنْ سَخَطِكَ، وَبِعَفْوِكَ مِنْ نِقْمَتِكَ، وَأَعُودُ بِكَ مِنْكَ، اَللَّهُمَّ لَا مَانِعَ لِمَا أَعْطَيْتَ، وَلَا مُعْطِيَ لِمَا مَنَعْتَ، وَلَا يَنْفَعُ ذَا الْجَدِّ مِنْكَ الْجَدُّ

Allaahumma Aslih li dinya-lladhi ja'altahu ismata amri, wa aslih li dunyaya-llati ja'alta fihaa ma'aashi, Allaahumma inni a-udhu biridaaka min sakhatika, wabi 'afwika min niqmatika, wa a-udhu bika minka, Allaahumma laa maani'a limaa a'taita wa laa mu'tia limaa mana'ta wa laa yanfa'u dhal-jaddi minka al-jaddu

O Allah, set straight my religious commitment that You have made a protection for me, and set straight my worldly affairs which You have made a means of my livelihood. O Allah, I seek refuge in Your pleasure from Your wrath, and I seek refuge in Your forgiveness from Your punishment, and I seek refuge in You from You. O Allah, None can withhold what you have given and none can give what you have withheld, and no wealth or fortune can avail the man of wealth and fortune before You.
