Purpose of the Quran

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

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.

إِلَّا تَذْكِرَةً لِّمَن يَخْشَىٰ

But only as a reminder for those who fear [Allāh] -
