Surah Al-Ahqaf, verse 8

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 ﴿٨﴾

46:8 Or do they say, “He has fabricated it”? Say, “If I did fabricate it, there is nothing you can do to protect me against Allah. He knows best what you gossip about it. He is Sufficient as a witness between me and you, and He is the All-Forgiving, the Most Merciful.”
