Supplication for the settling of a debt

اللَّهُمَّ اكْفِنِي بِحَلاَلِكَ عَنْ حَرَامِكَ, وَأَغْنِنِي بِفَضْلِكِ عَمَّنْ سِوَاكَ

(O Allah, make what is lawful enough for me, as opposed to what is unlawful, and spare me by Your grace, of need of others.)

Source: At-Tirmizi 5/560.

اللَّهُمَّ إِنِّي أَعُوذُ بِكَ مِنَ الْهَمِّ وَالْحَزَنِ, وَالْعَجْزِ وَالْكَسَلِ, وَالْبُخْلِ وَالْجُبْنِ, وَضَلَعِ الدَّيْنِ وَغَلَبَةِ الرِّجَالِ

(O Allah, I take refuge in You from anxiety and sorrow, weakness and laziness, miserliness and cowardice, the burden of debts and from being over powered by men.)

Source: Al-Bukhari 7/158.
