He has ordained for you all, the same System of Life that He enjoined upon Noah - And We have revealed to you (O Prophet) the same Message as We enjoined upon Abraham, Moses, and Jesus: "Establish the Divine System of Life and make no sects in it." (O Prophet) Hard it is upon the idolaters (those who worship false 'authorities') the unity you call to. Allah draws unto Himself everyone who is willing, and guides unto Himself everyone who turns unto Him." (Sects vs. Unity: (3:32), (3:104), (6:160), (30:31), (42:13), (45:17-18)).
