You missionaries are liars or idiots. You will never understand because devil is your guide. Allah is the God of all people from beginning of time and Islam meaning submission is the religion of all people from Adam and on. So if you find anything resembling true religion of God in other false religious practices, the straightforward conclusion should be that those false religions carry on some remnants of the true religion although they distorted the true message at large. Only stupids or liars would claim the other way around. BE MINDFUL OR BE HONEST. If you continue this slanderous approach there will be no talk here.
