Al Ahqaf Ayah 8

أَمْ يَقُولُونَ ٱفْتَرَٮٰهُ‌ۖ قُلْ إِنِ ٱفْتَرَيْتُهُۥ فَلَا تَمْلِكُونَ لِى مِنَ ٱللَّهِ شَيْــًٔا‌ۖ هُوَ أَعْلَمُ بِمَا تُفِيضُونَ فِيهِ‌ۖ كَفَىٰ بِهِۦ شَهِيدَۢا بَيْنِى وَبَيْنَكُمْ‌ۖ وَهُوَ ٱلْغَفُورُ ٱلرَّحِيمُ ٨ Or do they say, “He has fabricated this ?Quran?!”? Say, ?O Prophet,? “If I have done so, then there is nothing whatsoever you can do to save me from Allah. He knows best what ?slurs? you indulge about it. Sufficient is He as a Witness between you and me. And He is the All-Forgiving, Most Merciful.”
