وَمَآ أَنزَلْنَا عَلَيْكَ ٱلْكِتَـٰبَ إِلَّا لِتُبَيِّنَ لَهُمُ ٱلَّذِى ٱخْتَلَفُوا۟ فِيهِ ۙ وَهُدًى وَرَحْمَةً لِّقَوْمٍ يُؤْمِنُونَ ۝٦٤

16:64 And We have revealed the Scripture unto thee only that thou mayst explain unto them that wherein they differ, and (as) a guidance and a mercy for a people who believe.
