Du'a for abundance in sustenance and repayment of debt

ٱللَّهُ لَطِيفُۢ بِعِبَادِهِۦ يَرۡزُقُ مَن يَشَآءُۖ وَهُوَ ٱلۡقَوِيُّ ٱلۡعَزِيزُ

Allahu Lateef Be Ibaadihi Yarzoqqo Men Yashaa Wa Huwa Al Qawee Al Aziz

Allah is gracious unto His slaves. He provideth for whom He will. And He is the Strong, the Mighty
