19th Ayah from Surah Al An'am
Sahih International
Say, "What thing is greatest in testimony?" Say, " Allah is witness between me and you. And this Qur'an was revealed to me that I may warn you thereby and whomever it reaches. Do you [truly] testify that with Allah there are other deities?" Say, "I will not testify [with you]." Say, "Indeed, He is but one God, and indeed, I am free of what you associate [with Him]."
Abdul Haleem
Say, ‘What counts most as a witness?’ Say, ‘God is witness between you and me. This Quran was revealed for me to warn you [people] and everyone it reaches. Do you really bear witness that there are other gods beside God?’ Say, ‘I myself do not bear witness [to any such thing].’ Say, ‘He is only one God, and I disown whatever you join with Him.’
Mohsin Khan/Hilali
Say (O Muhammad SAW): "What thing is the most great in witness?" Say: "Allah (the Most Great!) is Witness between me and you; this Quran has been revealed to me that I may therewith warn you and whomsoever it may reach. Can you verily bear witness that besides Allah there are other aliha (gods)?" Say "I bear no (such) witness!" Say: "But in truth He (Allah) is the only one Ilah (God). And truly I am innocent of what you join in worship with Him."
Taqi Usmani
Say, “Whose testimony is the greatest?” Say, “Allah is the witness between me and you, and this Qur’ān has been revealed to me so that I should thereby warn you, and whomsoever it may reach. Do you really bear witness that there are other gods along with Allah?” Say, “I bear no such witness.” Say, “In fact, He is one God. I disown what you associate (with Him).”
Pickthall
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).
Pickthall
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."
