Surah An-Nahl, Verse 64

وَمَآ أَنزَلۡنَا عَلَيۡكَ ٱلۡكِتَٰبَ إِلَّا لِتُبَيِّنَ لَهُمُ ٱلَّذِي ٱخۡتَلَفُواْ فِيهِ وَهُدٗى وَرَحۡمَةٗ لِّقَوۡمٖ يُؤۡمِنُونَ٦٤

wamā anzalnā ʿalayka l-kitāba illā litubayyina lahumu alladhī ikh'talafū fīhi wahudan waraḥmatan liqawmin yu'minūna

And We have not revealed to you the Book, [O Muḥammad], except for you to make clear to them that wherein they have differed and as guidance and mercy for a people who believe.
