Qur'an preserved from fraud

إِنَّا نَحْنُ نَزَّلْنَا ٱلذِّكْرَ وَإِنَّا لَهُۥ لَحَٰفِظُونَ

We have, without doubt, sent down the Message; and We will assuredly guard it (from corruption).

وَٱتْلُ مَآ أُوحِىَ إِلَيْكَ مِن كِتَابِ رَبِّكَ ۖ لَا مُبَدِّلَ لِكَلِمَٰتِهِۦ وَلَن تَجِدَ مِن دُونِهِۦ مُلْتَحَدًۭا

And recite (and teach) what has been revealed to thee of the Book of thy Lord: none can change His Words, and none wilt thou find as a refuge other than Him.

وَمَآ أَرْسَلْنَا مِن قَبْلِكَ مِن رَّسُولٍۢ وَلَا نَبِىٍّ إِلَّآ إِذَا تَمَنَّىٰٓ أَلْقَى ٱلشَّيْطَٰنُ فِىٓ أُمْنِيَّتِهِۦ فَيَنسَخُ ٱللَّهُ مَا يُلْقِى ٱلشَّيْطَٰنُ ثُمَّ يُحْكِمُ ٱللَّهُ ءَايَٰتِهِۦ ۗ وَٱللَّهُ عَلِيمٌ حَكِيمٌۭ

Never did We send a messenger or a prophet before thee, but, when he framed a desire, Satan threw some (vanity) into his desire: but Allah will cancel anything (vain) that Satan throws in, and Allah will confirm (and establish) His Signs: for Allah is full of Knowledge and Wisdom:

ثُمَّ إِنَّ عَلَيْنَا بَيَانَهُۥ

Nay more, it is for Us to explain it (and make it clear):

فِى لَوْحٍۢ مَّحْفُوظٍۭ
