What is the ruling on leaving a university lecture that contains religious fallacies, while requesting the student's name to be registered as absent to avoid expulsion?

Attending a lecture that denigrates religion is not permissible, as it increases the number of Islam's enemies and aids them in their falsehood. The obligation is to avoid attending such a lecture and to leave the university if it is a place for such lectures. As for signing your name for attendance without actual presence to avoid expulsion, this is considered a lie that is permissible if it serves a benefit and no other means is available. If the university consistently holds such lectures, the general principle is to leave studies there. However, if you need to study there and find no alternative, there is no harm in continuing while absenting yourself from the forbidden lectures. In this case, it is permissible for you to sign your name.
