39:23
ٱللَّهُ نَزَّلَ أَحْسَنَ ٱلْ حَدِيثِ كِتَٰبًا مُّتَشَٰبِهًا مَّثَانِىَ تَقْشَعِرُّ مِنْ هُ جُلُودُ ٱلَّذِينَ يَخْشَ وْنَ رَبَّ هُمْ ثُمَّ تَلِينُ جُلُودُ هُمْ وَ قُلُوبُ هُمْ إِلَىٰ ذِكْرِ ٱللَّهِ ذَٰلِكَ هُدَى ٱللَّهِ يَهْدِى بِ هِۦ مَن يَشَآءُ وَ مَن يُضْلِلِ ٱللَّهُ فَ مَا لَ هُۥ مِنْ هَادٍ
Allah has sent down the best statement: a consistent Book wherein is reiteration. The skins shiver therefrom of those who fear their Lord; then their skins and their hearts relax at the remembrance of Allah. That is the guidance of Allah by which He guides whom He wills. And one whom Allah leaves astray - for him there is no guide.
