10. Junus · verses 37–38

وَمَا كَانَ هَٰذَا ٱلۡقُرۡءَانُ أَن يُفۡتَرَىٰ مِن دُونِ ٱللَّهِ وَلَٰكِن تَصۡدِيقَ ٱلَّذِي بَيۡنَ يَدَيۡهِ وَتَفۡصِيلَ ٱلۡكِتَٰبِ لَا رَيۡبَ فِيهِ مِن رَّبِّ ٱلۡعَٰلَمِينَ

Wama kana hatha alquranu an yuftara min dooni Allahi walakin tasdeeqa allathee bayna yadayhi watafseela alkitabi la rayba feehi min rabbi alAAalameena

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.

أَمۡ يَقُولُونَ ٱفۡتَرَىٰهُۖ قُلۡ فَأۡتُواْ بِسُورَةٖ مِّثۡلِهِۦ وَٱدۡعُواْ مَنِ ٱسۡتَطَعۡتُم مِّن دُونِ ٱللَّهِ إِن كُنتُمۡ صَٰدِقِينَ

Am yaqooloona iftarahu qul fatoo bisooratin mithlihi waodAAoo mani istataAAtum min dooni Allahi in kuntum sadiqeena

Or do they say, "He forged it"? say: "Bring then a Sura like unto it, and call (to your aid) anyone you can besides Allah, if it be ye speak the truth!"
