What is the ruling on befriending a girl who supports homosexuality or entering into a business venture with her?

A Muslim should strive to keep good company and avoid bad companions. For "Do not accompany anyone but a believer, and let no one eat your food except a pious person," and "A person is upon the religion of his intimate friend, so let one of you look at whom he befriends." If it is confirmed that the woman supports perversion, then do not befriend her, out of fear for your religion and your honor. As for engaging in business with her, it is permissible as long as she does not openly declare her support for perversion in your presence. However, she should be advised and the danger and deviance of homosexuality should be explained to her.
