وَمَآ أَنزَلۡنَا عَلَيۡكَ ٱلۡكِتَٰبَ إِلَّا لِتُبَيِّنَ لَهُمُ ٱلَّذِي ٱخۡتَلَفُواْ فِيهِ وَهُدٗى وَرَحۡمَةٗ لِّقَوۡمٖ يُؤۡمِنُونَ

We did not send down the Book to you except [for the purpose] that you may clarify for them what they differ about, and as a guidance and mercy for a people who have faith.
