13. He (Allâh) has ordained for you the same religion (Islâmic Monotheism) which He ordained for Nûh (Noah), and that which We have revealed to you (O Muhammad صلى الله عليه و سلم), and that which We ordained for Ibrâhîm (Abraham), Mûsâ (Moses) and ‘Îsâ (Jesus) saying you should establish religion (i.e. to do what it orders you to do practically), and make no divisions[1] in it (religion) (i.e. various sects in religion). Intolerable for the Mushrikûn,[2] is that (Islamic Monotheism) to which you (O Muhammad صلى الله عليه و سلم) call them. Allâh chooses for Himself whom He wills, and guides unto Himself who turns to Him in repentance and in obedience.
