Imam Malik, may Allah have mercy on him, said: If disbelievers are found on the shore of the sea in the land of the Muslims and they say, "We were merchants, the sea cast us here," but the Muslims do not verify this matter, although it is suspected that their ship broke or they disembarked due to thirst without the permission of the Muslims, then the Imam has discretion regarding them, and those who captured them will not receive a fifth (khums).
