And if not for a word that preceded from your Lord [postponing the penalty] until a specified time, it would have been concluded between them. And indeed, those who were granted inheritance of the Scripture after them are, concerning it, in disquieting doubt. So to that [religion of God] invite, and remain on a right course (wastaqim) as you are commanded and do not follow their inclinations (Ahwa'ahum).} (Ash-Shura: 13-15).

And this confirms that what He Almighty enjoined upon the prophets is the esoteric religion (al-Din al-Batin), in which there is no disagreement nor division; and not this exoteric religion (al-Din al-Zahir) of differing sayings and actions, the acceptance of which has become difficult for the polytheists.

And indeed, He Almighty commanded uprightness (al-Istiqamah) upon the esoteric upon the tongue of His prophets, and He forbade the following of inclinations in believing in the differing exoteric; and that is instruction (Ta'lim) and discipline (Ta'dib)

for His Almighty's saying: {[This is] the established way of God (Sunnat Allah) with those who passed on before; and you will not find in the way of God any change.} (Al-Ahzab: 62).

And His Almighty's saying: {[That is Our] established way for those We had sent before you of Our messengers; and you will not find in Our way any alteration.} (Al-Isra': 77).
