Does the participation of a person with ill-gotten money in the Udhiyah affect its validity if the Udhiyah is shared among a group?

It is permissible for seven people to share in an udhiyah (sacrificial animal) if it is a camel or a cow, with each of them receiving one-seventh of the udhiyah. It does not harm the sacrifice if one of the participants contributes with unlawfully acquired money, as long as the other partners are unaware of it, because each soul is responsible for its own actions. However, if they are aware, it is not permissible for them to assist him, and they must denounce his act.
