The Council on American-Islamic Relations is asking for disciplinary action after Metropolitan State University of Denver announced an investigation into alleged harassment of Muslim students praying on campus.

“Our religious freedoms grant us the right to practice our faith publicly and to be free of harassment or intimidation while doing so,” CAIR, a Muslim advocacy organization, said in a statement.

In a tweet from Dec. 2, a user wrote, “So we’re praying Maghreb [sic] and this lady starts going off trying to say ‘DO THIS SOMEWHERE ELSE’ and then starts bumping music. So we confront after and she begins with ‘F your religion..F you..I don’t care about your prayers’ just belligerence. Omar comes to pray and she continues.”

The Maghrib, performed just after sunset, is one of the five daily prayers of Islam. The user added that he prays in the computer lab, where the confrontation took place, typically without incident.

A video attached to the tweet pans between a male standing by a wall and quietly muttering prayers to a woman sitting at a computer. When the camera is on her, she extends both of her middle fingers. The man filming raises his voice while continuing to pray.

MSU Denver said that it “takes its commitment to diversity very seriously and places a high value on cultivating and sustaining a respectful and inclusive campus community.”
