Sometimes behave according to that religion ought to be done. It does not have a profound knowledge of the religion or are not interested in religion other than the religion itself.
Maybe they acted according to the religious of this action. But I don't have any profound religious knowledge or interest in other religions than their own religion.
Perhaps it was his practice, in accordance with the act, but not the religious should have knowledge about religion, deeply interested in religion or not. The other is not of his own religion
