"It's something that we must take very seriously," said CAIR-Chicago executive director Ahmed M. Rehab. "CAIR-Chicago is very disturbed by this news. The Muslim community is disturbed. People of conscience are disturbed. We've called police to investigate it, and to prosecute it as a hate crime, because that's what it is."

A stabbing at the Champaign train station this week is not a hate crime, according to the charges filed by the state’s attorney’s office. But an advocacy group disagrees. Amina Sharif, spokeswoman for the Chicago chapter of the Council on American-Islamic Relations, said Thursday it’s important to discourage prejudice.
