Ask, `Who is the best (witness) in respect of bearing testimony?' Say, `It is Allâh, He is Witness between me and you, and this Qur'ân has been revealed to me so that I may thereby warn you and all those whom it may reach (against the evil consequences of disbelief and misdeeds)' What (do you say)? Do you in fact bear witness that there are other gods besides Allâh? Say, `I do not bear witness thereto.' Say (moreover), `The fact is that He is the One and Only God; and surely I am sick and quit all those whom you associate (with Him).'
