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!"
