﴿ أَمْ يَقُولُونَ ٱفْتَرَىٰهُ ۖ قُلْ إِنِ ٱفْتَرَيْتُهُۥ فَعَلَىَّ إِجْرَامِى وَأَنَا۠ بَرِىٓءٌۭ مِّمَّا تُجْرِمُونَ ﴾

“DO SOME, perchance, assert, "[Muhammad] has invented this [story]"? Say [O Prophet]: "If I have invented it, upon me be this sin; but far be it from me to commit the sin of which you are guilty."”

God exalted be He says Or do they the disbelievers of Mecca say ‘He has invented it’? Muhammad (s) has invented the Qur’ān? Say ‘If I have invented it then my crime will be upon me my sin will be upon me that is the punishment for it; and I am innocent of what you commit’ of crime when you attribute invention to me.
