The Qur'an explains everything

وَلَقَدْ جِئْنَٰهُم بِكِتَٰبٍۢ فَصَّلْنَٰهُ عَلَىٰ عِلْمٍ هُدًۭى وَرَحْمَةًۭ لِّقَوْمٍۢ يُؤْمِنُونَ

For We had certainly sent unto them a Book, based on knowledge, which We explained in detail,- a guide and a mercy to all who believe.

وَمَا كَانَ هَٰذَا ٱلْقُرْءَانُ أَن يُفْتَرَىٰ مِن دُونِ ٱللَّهِ وَلَٰكِن تَصْدِيقَ ٱلَّذِى بَيْنَ يَدَيْهِ وَتَفْصِيلَ ٱلْكِتَٰبِ لَا رَيْبَ فِيهِ مِن رَّبِّ ٱلْعَٰلَمِينَ

This Qur'an is not such as can be produced by other than Allah; on the contrary it is a confirmation of (revelations) that went before it, and a fuller explanation of the Book - wherein there is no doubt - from the Lord of the worlds.

الٓر ۚ كِتَٰبٌ أُحْكِمَتْ ءَايَٰتُهُۥ ثُمَّ فُصِّلَتْ مِن لَّدُنْ حَكِيمٍ خَبِيرٍ

A. L. R. (This is) a Book, with verses basic or fundamental (of established meaning), further explained in detail,- from One Who is Wise and Well-acquainted (with all things):

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.

وَيَوْمَ نَبْعَثُ فِى كُلِّ أُمَّةٍۢ شَهِيدًا عَلَيْهِم مِّنْ أَنفُسِهِمْ ۖ وَجِئْنَا بِكَ شَهِيدًا عَلَىٰ هَٰٓؤُلَآءِ ۚ وَنَزَّلْنَا عَلَيْكَ ٱلْكِتَٰبَ تِبْيَٰنًۭا لِّكُلِّ شَىْءٍۢ وَهُدًۭى وَرَحْمَةًۭ وَبُشْرَىٰ لِلْمُسْلِمِينَ

One day We shall raise from all Peoples a witness against them, from amongst themselves: and We shall bring thee as a witness against these (thy people): and We have sent down to thee the Book explaining all things, a Guide, a Mercy, and Glad Tidings to Muslims.

وَلَقَدْ صَرَّفْنَا لِلنَّاسِ فِى هَٰذَا ٱلْقُرْءَانِ مِن كُلِّ مَثَلٍۢ فَأَبَىٰٓ أَكْثَرُ ٱلنَّاسِ إِلَّا كُفُورًۭا

And We have explained to man, in this Qur'an, every kind of similitude: yet the greater part of men refuse (to receive it) except with ingratitude!

وَلَقَدْ صَرَّفْنَا فِى هَٰذَا ٱلْقُرْءَانِ لِلنَّاسِ مِن كُلِّ مَثَلٍۢ ۚ وَكَانَ ٱلْإِنسَٰنُ أَكْثَرَ شَىْءٍۢ جَدَلًۭا

We have explained in detail in this Qur'an, for the benefit of mankind, every kind of similitude: but man is, in most things, contentious.

تِلْكَ ءَايَٰتُ ٱلْكِتَٰبِ ٱلْمُبِينِ

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

طسٓ ۚ تِلْكَ ءَايَٰتُ ٱلْقُرْءَانِ وَكِتَابٍۢ مُّبِينٍ

These are verses of the Qur'an,-a book that makes (things) clear;

تِلْكَ ءَايَٰتُ ٱلْكِتَٰبِ ٱلْمُبِينِ

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