Is the designer who adjusts the design of a sports shirt containing the logo of a liquor store or logos of alcohol and cigarette companies sinful, what is the ruling on that, and how can he avoid such requests in the future without losing his job?

It is not permissible to design or print logos for alcohol or immorality companies, as this promotes them and constitutes cooperation in sin, in accordance with His, the Almighty's, saying: "And cooperate in righteousness and piety, but do not cooperate in sin and aggression." Furthermore, the noble Hadith cursed ten individuals concerning intoxicants, not only the drinker but everyone who assists in it, and similarly with usury. Therefore, one must restrict oneself to permissible work, and whoever fears Allah, He will make for him a way out and provide for him from where he does not expect.
