Some people do indeed claim that the Qur’an was the work of the devil. Let us examine how much sense (or non-sense) this allegation makes.
If he authored or inspired the Qur’an, why would Satan curse himself and call himself the worst enemy of man?
Verily Satan is an enemy to you: so treat him as an enemy. He only invites his adherents, that they may become Companions of the Blazing Fire. …
(Al-Qur’an 35:6)
Did I not enjoin on you, O ye Children of Adam, that ye should not worship Satan; for that he was to you an enemy avowed?- …
(Al-Qur’an 36:60)
Why would Satan command that before reciting the Qur’an, one must first say:
“…I seek refuge in God from Satan the accursed.” …
(Al-Qur’an 16:98)
How could Satan so vehemently condemn himself? Is it really acceptable to common sense to hold the view that Satan would ask people to do good, to be moral and virtuous, to worship none but God, to not follow Satan or his whispers, and to avoid and struggle against evil?
To hold such a view is clearly repugnant to reason, as Satan has only undermined himself through this means if he is the author. Even the Bible attests:
“And if Satan has risen up against himself and is divided, he cannot stand, but is coming to an end.” …
(Mark 3:26)
This argument applies to any “Satanic forces”, be they “evil spirits”, “deceitful aliens”, etc
It really boils down to a question of faith because we need to
choose whether to believe in the truth of a text which has been proven to have remained
100% pure and unedited ever since it was first revealed to the Prophet Muhammad (pbuh) some 1400 years ago … or to believe in contradicting accounts that are found in other ancient scriptures whose authors are pretty much unknown.
As for the supposedly different Qur’an which was found in Yemen, researchers have found nothing particularly peculiar about it, have a look at this
