I'll have to take your word for that because I haven't seen any evidence of it.
None of the several moslems that I know or know of have said word one in denouncing their terrorist fundamentalist brothers. We do, however, hear about moslem FBI agents who are loyal to their moslem brothers first and the security of the U.S. second or less.
If there are ANY moslems denouncing islamo-terrorists, they sure are quiet about it.
