وَما كانَ هـٰذَا القُرآنُ أَن يُفتَرىٰ مِن دونِ اللَّهِ وَلـٰكِن تَصديقَ الَّذي بَينَ يَدَيهِ وَتَفصيلَ الكِتابِ لا رَيبَ فيهِ مِن رَبِّ العالَمينَ

This Quran could not have been fabricated by someone other than God. It confirms what came before it and thoroughly explains the Scripture. There is no doubt about it; it is from the Lord of the universes.
