Do they say that (the Messenger) has fabricated it (the Qur’an)? Say: ‘If I have concocted it then you have no authority to save me from (the torment of) Allah. And He knows best the (words) you utter about this (Qur’an) as mockery. He (Allah) is Sufficient as witness between me and you. And He is Most Forgiving, Ever-Merciful.’
