Abdullah Yusuf Ali:
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."
