Difference between interest and profit

Interest is the excess money to the principle.

Interest is any money over a credit/loan, whereas profit is any money you charge over your cost price.eg. If I give you 10,000 rupees and demands 12,000 in return than this is interest but if I sell you an motor bike specifying you that its cost price is 10,000 and I am selling it to you on 12,000. Than this is profit. In both the cases the incremental amount is 2000. So it doesn’t matter if the profit rates of Islamic banks match with the interest rates of conventional banks as long as the mechanism remains Islamic.

“You don’t need to work to earn interest but you need to work to earn profit.”
