Surah 3. Aal-Imran, Ayah 88

The Muslim position is clear. The Muslim does not claim to have a religion peculiar to himself. Islam is not a sect or an ethnic religion. In its view all Religion is one, for the Truth is one. It was the religion preached by all the earlier Prophets. It was the truth taught by all the inspired Books. In essence it amounts to a consciousness of the Will and Plan of Allah and a joyful submission to that Will and Plan. If any one wants a religion other than that, he is false to his own nature, as he is false to Allah's Will and Plan. Such a one cannot expect guidance, for he has deliberately renounced guidance. (A) Cf. ii. 161-62.
