What is the ruling on one who does not smoke but buys cigarettes to offer them to guests?

Purchasing and offering tobacco to guests or others is forbidden and a sin, because it falls under aiding in sin and aggression, which Allah has prohibited with His words: "And cooperate in righteousness and piety, but do not cooperate in sin and aggression." It is obligatory upon the Muslim to denounce evil, not to assist in it. And whoever buys it and offers it to others is a participant with the smoker in sin.
