What private revelation? Go to your nearest bookstore and pick up the Quran. Problem solved.<p>&quot;Other mammal&quot; here refers to what exactly? As for punishment, that happens when you intentionally deny the existence of the Creator, even when given the access to His word and religion. Islam teaches us that human beings are born pure and good by default, unlike other religions.<p>Suppose you lived your life on a remote island, never knowing about Islam or the Quran. In that case, you will be treated as if you lived your whole life as a Muslim in the hereafter. Why? Because you did not actively and intentionally deny it, and were not aware of its existence.<p>If you think religion is childish, OK. I don&#x27;t.
