ٱللَّهُ نَزَّلَ أَحْسَنَ ٱلْحَدِيثِ كِتَٰبًۭا مُّتَشَٰبِهًۭا مَّثَانِىَ تَقْشَعِرُّ مِنْهُ جُلُودُ ٱلَّذِينَ يَخْشَوْنَ رَبَّهُمْ ثُمَّ تَلِينُ جُلُودُهُمْ وَقُلُوبُهُمْ إِلَىٰ ذِكْرِ ٱللَّهِ ۚ ذَٰلِكَ هُدَى ٱللَّهِ يَهْدِى بِهِۦ مَن يَشَآءُ ۚ وَمَن يُضْلِلِ ٱللَّهُ فَمَا لَهُۥ مِنْ هَادٍ
Allah hath (now) revealed the fairest of statements, a Scripture consistent, (wherein promises of reward are) paired (with threats of punishment), whereat doth creep the flesh of those who fear their Lord, so that their flesh and their hearts soften to Allah's reminder. Such is Allah's guidance, wherewith He guideth whom He will. And him whom Allah sendeth astray, for him there is no guide.
Surah Az-Zumar(39:23)
