And remember when We made a covenant with you and raised the Mount Tur ( Sinai ) above you ; “ Accept and hold fast to what We give you , and listen ” ; they said , “ We hear and we disobey ; ” and the calf was still embedded in their hearts because of their disbelief ; say ( O dear Prophet Mohammed peace and – blessings be upon him ) , “ What an evil command is what your faith orders you , if you are believers ! ”
