16. In the sight of God there is only one system of life and way of conduct which is both in accord with reality and morally right. This consists of man's acknowledging God as his Lord and the sole object of his worship and devotion; of surrendering himself unreservedly to God in obedience and service. In doing so he should follow in toto the guidance communicated by God through His Messengers rather than try to devise ways of serving God according to his own lights. This mode of thought and action is known as Islam, and it is only reasonable that the Lord and Creator of the universe should accept nothing less from His creatures and servants. In his folly man thinks that he has the right to believe in and follow every doctrine that comes his way whether it be atheism or idolatry. In the sight of the Sovereign of the universe, however, all such attitudes amount to nothing short of rebellion against God.
17. This shows that the religion of every Messenger of God, in every age and clime, was none other than Islam (submission to God). Likewise, every Divine book, in whichever language it was revealed, and to whichever people it was addressed, contained the teachings of Islam. The various religions which have spread among mankind are distortions of this true, original religion, and are the result of tampering. Coveting privileges over and above those to which they were entitled, people altered the beliefs, principles and injunctions of the true religion in a manner conducive to their own interests.
