النحل — An-Nahl Ayat 64
وَمَآ اَنْزَلْنَا عَلَيْكَ الْكِتٰبَ اِلَّا لِتُبَيِّنَ لَهُمُ الَّذِى اخْتَلَفُوْا فِيْهِۙ وَهُدًى وَّرَحْمَةً لِّقَوْمٍ يُّؤْمِنُوْنَ
Wa mā anzalnā ‘alaikal-kitāba illā litubayyina lahumul-lażikhtalafū fīh(i), wa hudaw wa raḥmatal liqaumiy yu'minūn(a).
"And We have not revealed to you the Book, [O Muhammad], except for you to make clear to them that wherein they have differed and as guidance and mercy for a people who believe."
