Al-An'am - 6:19

قُلْ أَيُّ شَيْءٍ أَكْبَرُ شَهَادةً قُلِ اللّهِ شَهِيدٌ بِيْنِي وَبَيْنَكُمْ وَأُوحِيَ إِلَيَّ هَذَا الْقُرْآنُ لأُنذِرَكُم بِهِ وَمَن بَلَغَ أَئِنَّكُمْ لَتَشْهَدُونَ أَنَّ مَعَ اللّهِ آلِهَةً أُخْرَى قُل لاَّ أَشْهَدُ قُلْ إِنَّمَا هُوَ إِلَـهٌ وَاحِدٌ وَإِنَّنِي بَرِيءٌ مِّمَّا تُشْرِكُونَ
[6:19]
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).
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."
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).
