﴿ 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 ﴾

“God bestows from on high the best of all teachings in the shape of a divine writ fully consistent within itself, repeating each statement [of the truth] in manifold forms [a divine writ] whereat shiver the skins of all who of their Sustainer stand in awe: [but] in the end their skins and their hearts do soften at the remembrance of [the grace of] God. Such is God’s guidance: He guides therewith him that wills [to be guided] whereas he whom God lets go astray can never find any guide”
