Is it considered a sin for employees to accept a letter of credit for the export of alcoholic beer, despite their objection and coercion by upper management?

It is not permissible to work in an usurious bank because every job related to usury is religiously forbidden due to the aid and approval it entails. Allah Almighty said: "And do not cooperate in sin and aggression." And because the Prophet, peace and blessings be upon him, cursed the one who consumes usury, the one who feeds it, its scribe, and its two witnesses, and they are all equal. Allah has forbidden usury in all divine laws. It is obligatory to repent, leave this work, and seek permissible employment. Allah Almighty said: "And whoever fears Allah - He will make for him a way out And will provide for him from where he does not expect." However, if the bank is Islamic but has transgressions, it is obligatory to avoid participating in those transgressions, denounce them, and work in another legitimate field.
