What is the ruling on searching for ancient artifacts (Roman, Israeli) in the West Bank of Palestine, with the aim of earning money and selling them to unidentified parties, knowing that the Palestinian Authority prohibits and punishes this?

It is permissible for a Muslim to excavate ancient artifacts such as coins and vessels and sell them for profit, whether on land he owns or land owned by no one, as long as the state does not prohibit it for a public interest. It is also permissible to trade with non-Muslims as long as it does not involve forbidden matters. However, one should be cautious about selling Israeli artifacts to Jews due to the potential harm this could cause to the issue of occupied Palestine.
