( CNN ) -- A Muslim civil liberties group filed a lawsuit Friday against the federal government for allegedly violating the First Amendment rights of Michigan Muslims and violating a 1993 federal law that upholds the free practice of religion . The Council on American-Islamic Relations said U.S. border agents and the FBI infringed upon those rights with invasive questionings at the U.S.-Canada border . The group says Muslims have been detained , handcuffed and interrogated there without reason . `` They put me against the wall , and he handcuffed me and he went throughout my body , '' one of the plaintiffs , Ali Suleiman Ali , told CNN affiliate WDIV . The group says the agencies violated the 1993 Religious Freedom Restoration Act , which says the federal government can not substantially burden a person 's free exercise of religion . Agents allegedly asked `` How many times a day to you pray ? '' `` Do you pray your morning prayer in the mosque ? '' and `` Who else prays in your mosque ? '' according to CAIR . `` Invasive religious questioning of American citizens without evidence of criminal activity is not only an affront to the Constitution , but is also a waste of limited resources , '' CAIR-Michigan Executive Director Dawud Walid said . U.S. Customs and Border Protection responded Friday , saying that it `` strictly prohibits profiling on the basis of race or religion . '' `` In determining whether individuals are admissible into the United States , CBP utilizes specific facts and follows the Department of Justice 's 'Guidance Regarding the Use of Race by Federal Law Enforcement Agencies . ' `` The FBI declined to comment . CNN 's Carol Cratty contributed to this report .
