﴿ 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”

(Allah hath (now) revealed the fairest of statements) the best speech, i.e. the Qur'an, (a Scripture consistent) the verses of promise, mercy, victory and forgiveness are consistent with each others, and the verses of threat, chastisement, rebuke and warning are consistent with each other, wherein the mention of mercy and chastisement, promises and threats, the abrogating and abrogated, etc., are (paired), it is also said that this means: they are repeated, (whereat) from the verses of chastisement and threats (doth creep the flesh of those who fear their Lord, so that their flesh) soften through the verses of mercy (and their hearts soften) and their hearts return (to Allah's reminder) i.e. the Qur'an. (Such) i.e. the Qur'an (is Allah's guidance) is the clarification of Allah, (wherewith He guideth whom He will) to His religion. (And him whom Allah sendeth astray) from His religion, (for him there is no guide) to lead him to Allah's religion.
