What are the authentic supplications (duas) and Prophetic traditions (hadiths) that help in repaying debts and achieving financial ease, and is there a sin incurred by the deceased who intended to repay their debt, and what is the guidance and advice regarding this?

We pray to Allah to ease your debt and provide for you. There are prophetic supplications for settling debt, among them: "O Allah, suffice me with Your lawful provision against Your unlawful, and enrich me by Your grace, freeing me from need of anyone but You." And the supplication recited before sleep: "O Allah, Lord of the seven heavens... settle our debts for us, and enrich us from poverty." And the supplication: "O Allah, Possessor of all sovereignty... have mercy on me, a mercy by which You make me independent of the mercy of anyone other than You." And the supplication for worry and debt: "O Allah, I seek refuge in You from anxiety and sorrow... and I seek refuge in You from the overwhelming burden of debt and the subjugation of men." Among the supplications for an expansive livelihood are: "O Allah, rectify my religion for me, and expand for me in my affairs, and bless me in my provision." And among the supplications for seeking provision are: "O Allah, I ask You for beneficial knowledge, good provision, and accepted deeds," and "O Allah, forgive me, guide me, provide for me, and grant me well-being." If a debtor dies while intending and striving to repay his debt, Allah will pay it on his behalf.
