Qur'an as the word best

وَهَٰذَا كِتَٰبٌ أَنزَلْنَٰهُ مُبَارَكٌۭ فَٱتَّبِعُوهُ وَٱتَّقُوا۟ لَعَلَّكُمْ تُرْحَمُونَ

And this is a Book which We have revealed as a blessing: so follow it and be righteous, that ye may receive mercy:

وَإِذَا قُرِئَ ٱلْقُرْءَانُ فَٱسْتَمِعُوا۟ لَهُۥ وَأَنصِتُوا۟ لَعَلَّكُمْ تُرْحَمُونَ

When the Qur'an is read, listen to it with attention, and hold your peace: that ye may receive Mercy.

لَقَدْ كَانَ فِى قَصَصِهِمْ عِبْرَةٌۭ لِّأُو۟لِى ٱلْأَلْبَٰبِ ۗ مَا كَانَ حَدِيثًۭا يُفْتَرَىٰ وَلَٰكِن تَصْدِيقَ ٱلَّذِى بَيْنَ يَدَيْهِ وَتَفْصِيلَ كُلِّ شَىْءٍۢ وَهُدًۭى وَرَحْمَةًۭ لِّقَوْمٍۢ يُؤْمِنُونَ

There is, in their stories, instruction for men endued with understanding. It is not a tale invented, but a confirmation of what went before it,- a detailed exposition of all things, and a guide and a mercy to any such as believe.

ذَٰلِكَ مِمَّآ أَوْحَىٰٓ إِلَيْكَ رَبُّكَ مِنَ ٱلْحِكْمَةِ ۗ وَلَا تَجْعَلْ مَعَ ٱللَّهِ إِلَٰهًا ءَاخَرَ فَتُلْقَىٰ فِى جَهَنَّمَ مَلُومًۭا مَّدْحُورًا

These are among the (precepts of) wisdom, which thy Lord has revealed to thee. Take not, with Allah, another object of worship, lest thou shouldst be thrown into Hell, blameworthy and rejected.

ٱلْحَمْدُ لِلَّهِ ٱلَّذِىٓ أَنزَلَ عَلَىٰ عَبْدِهِ ٱلْكِتَٰبَ وَلَمْ يَجْعَل لَّهُۥ عِوَجَا ۜ

Praise be to Allah, Who hath sent to His Servant the Book, and hath allowed therein no Crookedness:

تِلْكَ ءَايَٰتُ ٱلْكِتَٰبِ ٱلْمُبِينِ

These are verses of the Book that makes (things) clear.

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 has revealed (from time to time) the most beautiful Message in the form of a Book, consistent with itself, (yet) repeating (its teaching in various aspects): the skins of those who fear their Lord tremble thereat; then their skins and their hearts do soften to the celebration of Allah's praises. Such is the guidance of Allah: He guides therewith whom He pleases, but such as Allah leaves to stray, can have none to guide.

وَٱتَّبِعُوٓا۟ أَحْسَنَ مَآ أُنزِلَ إِلَيْكُم مِّن رَّبِّكُم مِّن قَبْلِ أَن يَأْتِيَكُمُ ٱلْعَذَابُ بَغْتَةًۭ وَأَنتُمْ لَا تَشْعُرُونَ

"And follow the best of (the courses) revealed to you from your Lord, before the Penalty comes on you - of a sudden while ye perceive not!-
