I work as a technician in a company that transports passengers by air, and this company serves alcohol to the passengers. Please note that my work is technical, repairing seats and everything that has to do with the airplane. Am I a party to their sin? Is my wealth haraam? Please note that I asked a shaykh in our country and he told me that I am very far away from haraam.
Praise be to Allaah.
There is nothing wrong with working on maintenance of the
airplanes that transport passengers, and this work is not rendered haraam by
the haraam foods and drinks that may be served on board, because the work
itself is permissible, which is transporting passengers from one place to
another. And this is something that comes under the heading of necessity for
many people.
The airline company and the passengers should also refrain
from what Allah has forbidden.
Maintenance only becomes haraam work if it is helping a
sinner to commit sin, such as working on maintenance of military aircraft
for a state that is at war with the Muslims… and the like.
