Dh'ur taqeeb Dua2 by Imam Musa Kazim as -Allahumma in `azumat dhunubi fa-anta a`zamu

اَللَّهُمَّ إِنْ عَظُمَتْ ذُنُوبِي فَأَنْتَ أَعْظَمُ
O Allah! if my sins are enormous, surely You are more Tremendous.
وَإِنْ كَبُرَ تَفْرِيطِي فَأَنْتَ أَكْبَرُ
If my transgression has exceeded all limits, surely You are Greater.
وَإِنْ دَامَ بُخْلي فَأَنْتَ أَجْوَدُ
If my stinginess has perpetuated, surely You are more Generous.
اَللَّهُمَّ ٱغْفِرْ لِي عَظيمَ ذُنُوبِي بِعَظِيمِ عَفْوِكَ
O Allah, (please) forgive my enormous sins out of Your tremendous pardon,
وَكَثيرَ تَفْرِيطِي بِظَاهِرِ كَرَمِكَ
forgive my limitless transgression out of Your obvious generosity,
وَٱقْمَعْ بُخْلِي بِفَضْلِ جُودِكَ
and impede my stinginess by the virtue of Your magnanimity.
اَللَّهُمَّ مَا بِنَا مِنْ نِعْمَة فَمِنْكَ
O Allah, You are certainly the source of each and every favor that covers us.
لاَ إِلٰهَ إِلاَّ أَنْتَ
There is no god save You.
أَسْتَغْفِرُكَ وَ أَتُوبُ إِلَيْكَ
I pray Your forgiveness and I repent before You.
