قُلْ أَىُّ شَىْءٍ أَكْبَرُ شَهَـٰدَةً ۖ قُلِ ٱللَّهُ ۖ شَهِيدٌۢ بَيْنِى وَبَيْنَكُمْ ۚ وَأُوحِىَ إِلَىَّ هَـٰذَا ٱلْقُرْءَانُ لِأُنذِرَكُم بِهِۦ وَمَنۢ بَلَغَ ۚ أَئِنَّكُمْ لَتَشْهَدُونَ أَنَّ مَعَ ٱللَّهِ ءَالِهَةً أُخْرَىٰ ۚ قُل لَّآ أَشْهَدُ ۚ قُلْ إِنَّمَا هُوَ إِلَـٰهٌ وَٰحِدٌ وَإِنَّنِى بَرِىٓءٌ مِّمَّا تُشْرِكُونَ

Say, "What thing is greatest in testimony?" Say, "Allāh is witness between me and you. And this Qur’ān was revealed to me that I may warn you thereby and whomever it reaches. Do you [truly] testify that with Allāh 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]."

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.’

Say (O Muhammad صلى الله عليه وسلم): "What thing is the most great in witness?" Say: "Allâh (the Most Great!) is Witness between me and you; this Qur’ân has been revealed to me that I may therewith warn you and whomsoever it may reach. Can you verily bear witness that besides Allâh there are other âlihah (gods)?" Say "I bear no (such) witness!" Say: "But in truth He (Allâh) is the only one Ilâh (God). And truly I am innocent of what you join in worship with Him."
