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 they say, ‘He has invented it himself.’ Say [Prophet], ‘If I have really invented it, there is nothing you can do to save me from God. He knows best what you say amongst yourselves about it; He is sufficient as a witness between me and you; He is the Most Forgiving, the Most Merciful.’

Am yaqooloona iftarahu qul iniiftaraytuhu fala tamlikoona lee mina Allahi shay-anhuwa aAAlamu bima tufeedoona feehi kafa bihishaheedan baynee wabaynakum wahuwa alghafooru arraheem

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."
