وَمَا كَانَ هَـذَا الْقُرْآنُ أَن يُفْتَرَى مِن دُونِ اللّهِ وَلَـكِن تَصْدِيقَ الَّذِي بَيْنَ يَدَيْهِ وَتَفْصِيلَ الْكِتَابِ لاَ رَيْبَ فِيهِ مِن رَّبِّ الْعَالَمِينَ
[10:37]
And this Quran is not such as could be forged by those besides Allah, but it is a verification of that which is before it and a clear explanation of the book, there is no doubt in it, from the Lord of the worlds.
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.
And this Qur'an is not such as could ever be invented in despite of Allah; but it is a confirmation of that which was before it and an exposition of that which is decreed for mankind - Therein is no doubt - from the Lord of the Worlds.
