Question Detail:

Are all types of smuggling haram?
My friend is saying that smuggling is not Haram depending upon stuff. Please help me to understand this issue. 

Answer :

In the Name of Allah, the Most Gracious, the Most Merciful.
As-salāmu ‘alaykum wa-rahmatullāhi wa-barakātuh.
Smuggling is defined as “the illegal transportation of goods or people, such as out of a building, into a prison, or across an international border, in violation of applicable laws or other regulations”.[1]
In principle, it is prohibited to violate the laws of a country that are not unIslamic.
Accordingly and in general, smuggling is prohibited.[2]
And Allah Ta’āla Knows Best
