What is the ruling on a sale if the buyer discovers defects in the phone that only became apparent after examining it under different lighting conditions, given that there was a condition of option (khiyar), and the seller refused to refund the amount?

Resolving disputes falls under the jurisdiction of the judiciary, not the issuance of fatwas. This is because the judiciary hears from both parties and ascertains the facts and evidence, whereas a mufti (definition) hears from only one party.

A defect affecting the price, of which the buyer was unaware until after the purchase, permits him to return the sold item and reclaim the price. Scholars have reached a consensus on this matter. The option of stipulated condition (khiyar al-shart (definition)) for a period of three days is valid and binding if agreed upon by both parties in the contract.
