Is Salih obligated to repay the amount to Ali's family after Ali's death and the company's waiving of his debt?

The company's write-off of the amount owed by Ali constitutes an absolution of his financial liability and that of his heirs. If Ali had lent this amount to Salih, then Salih's financial liability has become engaged with it. Therefore, Ali's heirs have the right to demand that Salih repay the debt, as it is inherited wealth for them, based on the Prophet's (peace be upon him) saying: "Whoever leaves behind wealth, it is for his heirs." It is not permissible for Salih to delay repayment if he can afford it, because "the procrastination of a rich person is an injustice."
