It is narrated from Sayyiduna Samurah bin Jundub (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Whoever loses some goods and then finds that very item in a man's hand, he has more right to it, and the buyer will turn to the seller for the price."
