أَمْ يَقُولُونَ ٱفْتَرَىٰهُ ۖ قُلْ إِنِ ٱفْتَرَيْتُهُۥ فَلَا تَمْلِكُونَ لِى مِنَ ٱللَّهِ شَيْـًٔا ۖ هُوَ أَعْلَمُ بِمَا تُفِيضُونَ فِيهِ ۖ كَفَىٰ بِهِۦ شَهِيدًۢا بَيْنِى وَبَيْنَكُمْ ۖ وَهُوَ ٱلْغَفُورُ ٱلرَّحِيمُ

Or do they say, "He has invented it?" Say, "If I have invented it, you will not possess for me [the power of protection] from Allah at all. He is most knowing of that in which you are involved. Sufficient is He as Witness between me and you, and He is the Forgiving the Merciful."

— Al-Aḥqāf 46:8
