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

And it was not [possible] for this Qur'an to be produced by other than Allah, but [it is] a confirmation of what was before it and a detailed explanation of the [former] Scripture, about which there is no doubt, from the Lord of the worlds.
