Assume the goods were first acquired for Rs 8,000.
1. Ordinary sale: an agreement is made at Rs 9,000 without basing the contract on the earlier price.
2. Murabahah: the seller discloses Rs 8,000 cost and Rs 1,000 profit, making Rs 9,000 payable.
3. Tawliyah: the item is transferred for the stated original Rs 8,000.
The critical difference is not merely the final amount but the representation on which the buyer relies.
