Quran, is not such as could ever be produced than Allah

And if you are in doubt about what We have sent down [i.e., the Qur’ān] upon Our Servant [i.e., Prophet Muḥammad (ﷺ)], then produce a sūrah the like thereof and call upon your witnesses [i.e., supporters] other than Allāh, if you should be truthful.

Or do they say, "He invented it"? Say, "Then bring ten sūrahs like it that have been invented and call upon [for assistance] whomever you can besides Allāh, if you should be truthful."

Say, "If mankind and the jinn gathered in order to produce the like of this Qur’ān, they could not produce the like of it, even if they were to each other assistants."
