The Taliban impose a tax on all tankers and trucks carrying goods and passing through the territory they control.

Answer

The Taliban are in a state of war. They have valid reasons for the taxation. In fact, it is permissible for them in the current circumstances to loot all the stock on the trucks and regard it as spoils of war. This would enable them to pursue the war against the U.S. kuffaar and the Afghan traitors on a better level.
