Is the islamic ruling on

Q 3: What is the ruling on borrowing money from someone whose current whereabouts is unknown?

A: If you need to repay a debt or a loan to someone and you do not know their whereabouts or how to find them, and you despair of being able to repay them the debt, you should give it out as Sadaqah (voluntary charity) with the intention that the creditor receives its reward. If they eventually appear, tell them what happened; they will either accept the Sadaqah, or else you should pay them the debt and you will receive the reward for the Sadaqah. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
