The seller claimed Rs 1,000 as the first price and quoted a 20% markup, making Rs 1,200 payable. The actual first price later proved to be Rs 800.
Under Abu Hanifah, the buyer can keep the goods for Rs 1,200 or exercise the right to rescind.
The price does not automatically change to Rs 960 merely because the true cost became known. That revised figure illustrates Abu Yusuf’s different view.
