(bismillah) There is a common phenomena in our society where teenagers lend money to their friends in small amounts for buying a piece of candy, or some other object. At a later time, the lendee says that they want to pay back, however, the lender says that the amount of money is little and is not significant or either the lendee himself considers it insignificant. In this scenario, I raise many questions; 1) When the lender declares that the money they lent is little to be significant. a) How should the other person act? Should they force them to accept the money? b ) Are they blamed for not giving the money? c) Is this kind of loan in Islam acceptable? and is it even considered a loan? 2) When the lendee perhaps considers that the money is too little to be paid back . a) Can the other person ask for his money back even if it is little? Is this considered stinginess? b ) Should a person give a time limit as to when it should be paid back even if it is little? Forgive my ignorance to these questions, but this subject is a blank in my mind. If you can also direct me to a book that is considered with such topics or lectures, it would be very helpful. Thank you for your answers Wassalam
