Which has priority in repayment when repenting: usurious debt or stolen money? And does the ruling differ if the owner of the stolen money is on their deathbed or their heirs cannot be reached?

A Muslim must repent from all sins. A condition for repenting from transgressions against people's rights is to immediately return what was unjustly taken. In the case of a usurious loan, one must repent and repay only the principal, and there is no obligation to repay the unlawful increase. If one is forced to pay it, there is no sin. Repaying stolen money takes precedence over repaying a usurious loan because the rights of individuals are based on strict accountability. If the owner of the stolen money is on their deathbed, it is imperative to return their money and seek their forgiveness before their death.
