اللَّهُ نَزَّلَ أَحسَنَ الحَديثِ كِتابًا مُتَشابِهًا مَثانِيَ تَقشَعِرُّ مِنهُ جُلودُ الَّذينَ يَخشَونَ رَبَّهُم ثُمَّ تَلينُ جُلودُهُم وَقُلوبُهُم إِلىٰ ذِكرِ اللَّهِ ۚ ذٰلِكَ هُدَى اللَّهِ يَهدي بِهِ مَن يَشاءُ ۚ وَمَن يُضلِلِ اللَّهُ فَما لَهُ مِن هادٍ

God revealed the most excellent message: a book consistent in its teachings, offering repeated reinforcement and serving as a reminder. The skins of those who revere their Lord shiver due to it. Then, their skins and hearts soften to God’s remembrance. This is God’s guidance, through which He guides whom He wills. But he whom God leaves to stray has no guide.
