The right of him to whom you owe a debt (al-gharim alladhi yutalibuka) is that, if you have the means, you pay him back, and if you are in straitened circumstances, you satisfy him with good words and you send him away with gentleness.

وأما حق غريمك الذي يطالبك فإن كنت موسرا أعطيته وإن كنت معسرا أرضيته بحسن القول ورددته عن نفسك ردا لطيفا
