Dua to have Allah repay debts even like mountains

A man had a claim against me, and I feared him. So I stayed home and remained for two days without going out. Then I went out and came to the Messenger of Allah ﷺ, and he said: “O Muʿādh, what kept you back?” I said: A man had a right over me; I feared him until I became ashamed, and I disliked that he should meet me. He said: “Shall I not instruct you in some words you can say—if you have debts like mountains, Allah will pay them off for you?”

I said: Yes. He said: "Say: (O Allah, Owner of Sovereignty, You give sovereignty to whom You will and You take sovereignty away from whom You will,’ up to His saying, ‘without reckoning,’ to the end, [Al Imran 3:26-27] Merciful of this world and the Hereafter and Compassionate to them both; You grant of them to whom You will and You withhold of them from whom You will. O Allah, enrich me so that I have no need of poverty, pay off my debt for me, and cause me to die in Your service and in striving in Your path.)"

كَانَ لِرَجُلٍ عَلَيَّ بَعْضُ الْحَقِّ، فَخَشِيتُهُ، فَجَلَسْتُ، فَلَبِثْتُ يَوْمَيْنِ لَا أَخْرُجُ، ثُمَّ خَرَجْتُ، فَجِئْتُ رَسُولَ اللَّهِ ﷺ، فَقَالَ: «يَا مُعَاذُ، مَا خَلَّفَكَ؟». فَقُلْتُ: كَانَ لِرَجُلٍ عَلَيَّ حَقٌّ، خَشِيتُهُ، حَتَّى اسْتَحْيَيْتُ، وَكَرِهْتُ أَنْ يَلْقَانِي. فَقَالَ: «أَلَا آمُرُكَ بِكَلِمَاتٍ تَقُولُهُنَّ، إِنْ كَانَ عَلَيْكَ أَمْثَالُ الْجِبَالِ، قَضَاهُ اللَّهُ؟».

قُلْتُ: بَلَى. قَالَ: «قُلِ: ﴿ اللَّهُمَّ مَالِكَ الْمُلْكِ، تُؤْتِي الْمُلْكَ مَنْ تَشَاءُ، وَتَنْزِعُ الْمُلْكَ مِمَّنْ تَشَاءُ ﴾ إِلَى قَوْلِهِ: ﴿ بِغَيْرِ حِسَابٍ ﴾ إِلَى الْآخِرِ، رَحْمَنَ الدُّنْيَا وَالْآخِرَةِ وَرَحِيمَهُمَا، تُعْطِي مِنْهُمَا مَنْ تَشَاءُ، وَتَمْنَعُ مِنْهُمَا مَنْ تَشَاءُ، اللَّهُمَّ أَغْنِنِي عَنِ الْفَقْرِ، وَاقْضِ عَنِّي الدَّيْنَ، وَتَوَفَّنِي فِي عِبَادِكَ وَجِهَادٍ فِي سَبِيلِكَ».
