وَكَيْفَ تَكْفُرُونَ وَأَنتُمْ تُتْلَىٰ عَلَيْكُمْ ءَايَـٰتُ ٱللَّهِ وَفِيكُمْ رَسُولُهُۥ ۗ وَمَن يَعْتَصِم بِٱللَّهِ فَقَدْ هُدِىَ إِلَىٰ صِرَٰطٍ مُّسْتَقِيمٍ

And how could you disbelieve while to you are being recited the verses of Allāh and among you is His Messenger? And whoever holds firmly to Allāh1 has [indeed] been guided to a straight path.

آل عمران 101

ٱتَّبِعْ مَآ أُوحِىَ إِلَيْكَ مِن رَّبِّكَ ۖ لَآ إِلَـٰهَ إِلَّا هُوَ ۖ وَأَعْرِضْ عَنِ ٱلْمُشْرِكِينَ

Follow, [O Muḥammad], what has been revealed to you from your Lord - there is no deity except Him - and turn away from those who associate others with Allāh.

الأنعام 106

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.1 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]."

الأنعام 19

وَمَا كَانَ هَـٰذَا ٱلْقُرْءَانُ أَن يُفْتَرَىٰ مِن دُونِ ٱللَّهِ وَلَـٰكِن تَصْدِيقَ ٱلَّذِى بَيْنَ يَدَيْهِ وَتَفْصِيلَ ٱلْكِتَـٰبِ لَا رَيْبَ فِيهِ مِن رَّبِّ ٱلْعَـٰلَمِينَ

And it was not [possible] for this Qur’ān to be produced by other than Allāh, but [it is] a confirmation of what was before it and a detailed explanation of the [former] Scripture, about which there is no doubt,1 from the Lord of the worlds.

يونس 37

أَكَانَ لِلنَّاسِ عَجَبًا أَنْ أَوْحَيْنَآ إِلَىٰ رَجُلٍ مِّنْهُمْ أَنْ أَنذِرِ ٱلنَّاسَ وَبَشِّرِ ٱلَّذِينَ ءَامَنُوٓا۟ أَنَّ لَهُمْ قَدَمَ صِدْقٍ عِندَ رَبِّهِمْ ۗ قَالَ ٱلْكَـٰفِرُونَ إِنَّ هَـٰذَا لَسَـٰحِرٌ مُّبِينٌ

Have the people been amazed that We revealed [revelation] to a man from among them, [saying], "Warn mankind and give good tidings to those who believe that they will have a [firm] precedence of honor1 with their Lord"? [But] the disbelievers say, "Indeed, this is an obvious magician."
