What is the ruling on bringing a bottle of wine for a Christian manager on an overseas business trip under pressure from him, and is this action considered a minor sin, a major sin, or a disliked act, taking into account that this situation is not a recurring one?

Do not obey the manager in an act of disobedience to Allah by purchasing alcohol for him. For whoever pleases people by incurring the wrath of Allah, Allah will be wrathful with him and make people wrathful with him. Allah is the best Trustee and Protector for whoever obeys Him. Purchasing alcohol is a major sin. The Prophet, peace and blessings be upon him, cursed ten categories of people concerning alcohol, among them its purchaser and its carrier.
