Ahmed Rehab, Executive Director of CAIR-Chicago said, "We feel sickened by this attack, and will not be silent. Those who perpetrated these cowardly murders cannot purport to call themselves men of God or men of faith."

“The reprehensible attack against this Jewish congregation is an insult to all of us,” said Ahmed Rehab, executive director of CAIR-Chicago. “An attack against one house of worship is an attack against every house of worship.”

"We condemn this cowardly attack in the strongest terms possible and ask that the perpetrators be punished to the full extent of the law, " said CAIR in a statement today. "American Muslims stand with our fellow citizens in offering both prayers for the victims and sincere condolences to the families of those killed or injured.”
