We gave an interest free loan to a customer & hopefully we will be getting 10%interest gratuity. That 10% will be our first revenue/income/profit !
Is the borrower obligated to give that 10%? What happens if they don't? I thought the whole business about being interest-free is that the recipient of the benevolent loan (qardhul 7asanah) provides the gratuity at their absolute discretion and as a token of goodwill. How did you arrive at that 10% figure?
