Al An’am Ayah 19

قُلْ أَىُّ شَىْءٍ أَكْبَرُ شَهَـٰدَةً‌ۖ قُلِ ٱللَّهُ‌ۖ شَهِيدُۢ بَيْنِى وَبَيْنَكُمْ‌ۚ وَأُوحِىَ إِلَىَّ هَـٰذَا ٱلْقُرْءَانُ لِأُنذِرَكُم بِهِۦ وَمَنۢ بَلَغَ‌ۚ أَئِنَّكُمْ لَتَشْهَدُونَ أَنَّ مَعَ ٱللَّهِ ءَالِهَةً أُخْرَىٰ‌ۚ قُل لَّآ أَشْهَدُ‌ۚ قُلْ إِنَّمَا هُوَ إِلَـٰهٌ وَٲحِدٌ وَإِنَّنِى بَرِىٓءٌ مِّمَّا تُشْرِكُونَ ١٩ Ask ?them, O Prophet?, “Who is the best witness?” Say, “Allah is! He is a Witness between me and you. And this Quran has been revealed to me so that, with it, I may warn you and whoever it reaches. Do you ?pagans? testify that there are other gods besides Allah?” ?Then? say, “I will never testify ?to this?!” ?And? say, “There is only One God. And I totally reject whatever ?idols? you associate with Him.”
