Is working on packaging magazines that advertise a "bar" and include its drink menus considered an illicit gain, or should one donate it as charity?

It is not permissible to bind a magazine that promotes the unlawful and calls to falsehood, due to the Almighty's saying: "And do not cooperate in sin and aggression." If the predominant nature of your work involves unlawful matters, it is not permissible to remain in it, and the earnings from it are forbidden and must be disposed of by spending them on the welfare of Muslims and giving them to the poor and needy. However, if this is an incidental matter, then you must refrain from it in the future, and it is permissible for you to remain in the job, and the earnings are permissible if they have no value; otherwise, dispose of what corresponds to them from the earnings.
