Say, 'What thing is the weightiest in testimony.' Say, 'Allah is a Witness between me and you. And this Qur'án has been revealed to me so that with it I may warn you, as well as whomsoever it reaches, of the impending punishment. What! do you really bear witness that there are other gods besides Allah?' Say, 'I bear not witness thereto.' Say, 'He is the One Allah, and certainly I am innocent of that which you associate with Him.'
