Al-Baqarah 2:213 كان الناس امة واحدة فبعث الله النبيين مبشرين ومنذرين وانزل معهم الكتاب بالحق ليحكم بين الناس فيما اختلفوا فيه وما اختلف فيه الا الذين اوتوه من بعد ما جاءتهم البينات بغيا بينهم فهدى الله الذين امنوا لما اختلفوا فيه من الحق باذنه والله يهدي من يشاء الى صراط مستقيم ٢١٣

In the beginning mankind followed one single way. (Later on this state ended and differences arose.) Then Allah sent forth Prophets as heralds of good tidings for the righteous and as warners against the consequences of evil-doing. He sent down with them the Book embodying the Truth so that it might judge among people in their disputes. And those who innovated divergent ways rather than follow the Truth were none other than those who had received the knowledge of the Truth and clear guidance; and they did so to commit excesses against each other.¹ So by His leave Allah directed the believers to the Right Way in matters on which they disagreed. Allah guides whomsoever He wills onto a Straight Way.
