قُلْ اَيُّ شَيْءٍ اَكْبَرُ شَهَادَةً ۗ قُلِ اللّٰهُ ۗشَهِيْدٌۢ بَيْنِيْ وَبَيْنَكُمْ ۗوَاُوْحِيَ اِلَيَّ هٰذَا الْقُرْاٰنُ لِاُنْذِرَكُمْ بِهٖ وَمَنْۢ بَلَغَ ۗ اَىِٕنَّكُمْ لَتَشْهَدُوْنَ اَنَّ مَعَ اللّٰهِ اٰلِهَةً اُخْرٰىۗ قُلْ لَّآ اَشْهَدُ ۚ قُلْ اِنَّمَا هُوَ اِلٰهٌ وَّاحِدٌ وَّاِنَّنِيْ بَرِيْۤءٌ مِّمَّا تُشْرِكُوْنَ ( الأنعام: ١٩ )

Sahih International:
Say, "What thing is greatest in testimony?" Say, "Allah is witness between me and you. And this Quran 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]." (Al-An'am [6] : 19)

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).”
