May Allah bless you. Regarding receiving payment from non-Muslims who have haram sources of income, there are varying opinions. Personally, I hold the belief that it is permissible to accept gifts or wages from non-Muslims, even if their income is obtained through haram means, as they are not obligated to follow Shariah laws. And Allah knows best!
