The Difference Between the Customs Duty and the Tax in Commercial Transactions

Question:
May Allah reward you, Honorable Shaykh. We have learned that the *mukus* is taking people's money unjustly,

Answer:
Is that right? Unjustly. It is taking what they call the tax that is levied on the owners of goods, on the merchants. It is not all unjust taking, no, this is specific to taking it from merchants and owners of goods. May Allah reward you. If disbelievers trade with us in our lands, we have the right to take from them, but a Muslim is not to be taken from. Unless this is for the sake of maintaining security, or something else observed by the state that we do not know of, Allah knows best. But taking it for the sake of money is not permissible. However, if it is taken to control something, to preserve security, or out of fear that prohibited goods will sneak into the country, that is a different matter.
