Translator	Translation
Ali Quli Qara'i	Say, ‘What thing is greatest as witness?’ Say, ‘Allah! [He is] witness between me and you, and this Qur’ān has been revealed to me that I may warn thereby you and whomever it may reach.’ ‘Do you indeed bear witness that there are other gods besides Allah?’ Say, ‘I do not bear witness [to any such thing].’ Say, ‘Indeed He is the One God, and I indeed disown what you associate [with Him].’
Pickthal	Say (O Muhammad): What thing is of most weight in testimony? Say: Allah is Witness between me and you. And this Qur'an hath been inspired in me, that I may warn therewith you and whomsoever it may reach. Do ye in sooth bear witness that there are gods beside Allah? Say: I bear no such witness. Say: He is only One Allah. Lo! I am innocent of that which ye associate (with Him).
Shakir	Say: What thing is the weightiest in testimony? Say: Allah is witness between you and me; and this Quran has been revealed to me that with it I may warn you and whomsoever it reaches. Do you really bear witness that there are other gods with Allah? Say: I do not bear witness. Say: He is only one Allah, and surely I am clear of that which you set up (with Him).
Yusufali	Say: "What thing is most weighty in evidence?" Say: "Allah is witness between me and you; This Qur'an hath been revealed to me by inspiration, that I may warn you and all whom it reaches. Can ye possibly bear witness that besides Allah there is another Allah?" Say: "Nay! I cannot bear witness!" Say: "But in truth He is the one Allah, and I truly am innocent of (your blasphemy of) joining others with Him."
