Is it permissible for a customs officer to receive rewards from funds collected from fines imposed on smugglers and document forgers? And does the ruling differ if these rewards result from the injustice of some employees toward an individual? And is it permissible to take goods left at customs or give them to the needy instead of destroying them?

Collecting customs duties, in most cases, involves taking people's money without a lawful right. Therefore, it is impermissible to work in this field, as it constitutes assisting in wrongdoing. Punishing with money (financial penalties) is forbidden according to the majority of scholars, based on the Almighty's saying: "And do not consume your properties among yourselves through falsehood," and the Prophet's (peace be upon him) saying: "Indeed, your blood, your properties, and your honor are sacred among you." It is advised to leave work in customs. As for rewards, it is not permissible to take them or benefit from them. If there is a fear of them being confiscated, they should be taken and given as charity on behalf of their owners if they cannot be returned. Regarding abandoned goods that are feared to spoil or be lost, there is no harm in taking them and giving them to those in need.
