(Yoonus) 10 : 37
وَمَا كَانَ هَٰذَا الْقُرْآنُ أَنْ يُفْتَرَىٰ مِنْ دُونِ اللَّهِ وَلَٰكِنْ تَصْدِيقَ الَّذِي بَيْنَ يَدَيْهِ وَتَفْصِيلَ الْكِتَابِ لَا رَيْبَ فِيهِ مِنْ رَبِّ الْعَالَمِينَ

And it was not this Reading for forging by other than Lord Allah, but It is a confirmation of what was before It and a detailed explanation of the Book, no doubt in It, It is from the Lord of all worlds.

Verses 32: 2-3 say: “The Book is sent down, there is no doubt in It that It is from the Lord of all worlds. Or are they saying that he has forged It; nay, It is the Truth from your Lord in the order you to warn a people into whom no warner had come before you, so that they may be guided”. Adhikr sent down to Messenger Muhammad contains all the 312 previous Books and their upright Explanations as told in verses 16: 44 and 98: 2-3. It safeguards and testifies all the previous Books as explained in verse 5: 48. See explanation 2: 1-2; 3: 58 and 7: 52.
