Is it a sin for a food inspector at Dubai Airport to inspect pork, for the purpose of allowing its entry into the country in accordance with the laws?

There is no harm in working as a food inspector, but it is not permissible to allow pork into the country, because it is aiding in sin and transgression, as Allah Almighty says: "And do not cooperate in sin and transgression." If you can prevent its entry on the pretext that it is unsuitable, then you will be rewarded. Otherwise, it is obligatory to leave this job, as Allah Almighty says: "And whoever fears Allah - He will make for him a way out And will provide for him from where he does not expect."
