Al-Ahqaf 46:8 ام يقولون افتراه قل ان افتريته فلا تملكون لي من الله شييا هو اعلم بما تفيضون فيه كفى به شهيدا بيني وبينكم وهو الغفور الرحيم ٨

Or do they say, “He¹ 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.”

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 Allāh at all. He is most knowing of that in which you are involved.¹ Sufficient is He as Witness between me and you, and He is the Forgiving, the Merciful."
