Inability to know the owner of the money from whom a deceased had borrowed

Q 1: A man passed away before repaying debts which he owed to the State Agricultural Bank and Land Bank, and some other individuals. We, along with the deceased's inheritors, paid the debts that he owed to individuals. Only one creditor remains to whom we must pay the value of two she-camels that the deceased borrowed about thirty five years ago. However, we do not know the person to whom the debt is due or where to locate him so that Allah might grant the deceased comfort in his grave.

A: In this case, where the owner of the two she-camels or his inheritors can not be found, you must pay the value of the two she-camels in Sadaqah (voluntary charity) at the time in which the debt was incurred. The cost of an average she-camel should be calculated and distributed amongst the poor on behalf of the camels' owner. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
