What is the ruling on partnering with a customs officer, on a 50/50 basis, to purchase goods from abroad, where he undertakes their entry into Algeria? And what is the ruling on sending money via bank transfer in foreign commercial dealings? And what is the ruling on buying foreign currency with the payment of its price deferred for a week?

The question requires clarification of the capital contributed by the questioner and the customs official. If the customs official's job and his facilitation of goods entry play a role in the partnership, whereby he takes a percentage of the profit, then this is impermissible, whether or not he contributed capital. This is because what the state takes from suppliers is either in exchange for services, in which case it is impermissible to evade them or show favoritism to the customs official in them, or it is not in exchange for anything, in which case the customs duty is unlawful, being a form of "maks" (unjust tax) and usurpation. Therefore, partnership in the manner described is not permissible.
