hey K..whoever Allah (SWT) guides will convert and accept the path of righteousness. If someone is criminal then that doesn’t mean that he cannot change himself. If he or she realizes that what he or she was doing was wrong and accept the path of righteousness then whats wrong in that ? You statement is bias. It seems like you are jealous and you envy the growing population of Islam. But don’t worry only Islam will prevail and all the fake religions will fade away.
