Ask them: 'Whose testimony is the greatest?' Say: 'Allah is the witness between me and you; and this Qur'an was revealed to me that I should warn you thereby and also whomsoever it may reach.' Do you indeed testify that there are other gods with Allah? Say: 'I shall never testify such a thing.' Say: 'He is the One God and I am altogether averse to all that you associate with Him in His divinity.'
