وَإِن كُنتُمْ فِى رَيْبٍ مِّمَّا نَزَّلْنَا عَلَىٰ عَبْدِنَا فَأْتُوا۟ بِسُورَةٍ مِّن مِّثْلِهِۦ وَٱدْعُوا۟ شُهَدَآءَكُم مِّن دُونِ ٱللَّهِ إِن كُنتُمْ صَـٰدِقِينَ

And if you are in doubt about what We have sent down [i.e., the Qur’ān] upon Our Servant [i.e., Prophet Muḥammad (ﷺ)], then produce a sūrah the like thereof and call upon your witnesses [i.e., supporters] other than Allāh, if you should be truthful.

البقرة 23

وَإِنَّ مِنْهُمْ لَفَرِيقًا يَلْوُۥنَ أَلْسِنَتَهُم بِٱلْكِتَـٰبِ لِتَحْسَبُوهُ مِنَ ٱلْكِتَـٰبِ وَمَا هُوَ مِنَ ٱلْكِتَـٰبِ وَيَقُولُونَ هُوَ مِنْ عِندِ ٱللَّهِ وَمَا هُوَ مِنْ عِندِ ٱللَّهِ وَيَقُولُونَ عَلَى ٱللَّهِ ٱلْكَذِبَ وَهُمْ يَعْلَمُونَ

And indeed, there is among them a party who alter the Scripture with their tongues so you may think it is from the Scripture, but it is not from the Scripture. And they say, "This is from Allāh," but it is not from Allāh. And they speak untruth about Allāh while they know.

آل عمران 78

مَا كَانَ لِبَشَرٍ أَن يُؤْتِيَهُ ٱللَّهُ ٱلْكِتَـٰبَ وَٱلْحُكْمَ وَٱلنُّبُوَّةَ ثُمَّ يَقُولَ لِلنَّاسِ كُونُوا۟ عِبَادًا لِّى مِن دُونِ ٱللَّهِ وَلَـٰكِن كُونُوا۟ رَبَّـٰنِيِّـۧنَ بِمَا كُنتُمْ تُعَلِّمُونَ ٱلْكِتَـٰبَ وَبِمَا كُنتُمْ تَدْرُسُونَ

It is not for a human [prophet]1 that Allāh should give him the Scripture2 and authority and prophethood and then he would say to the people, "Be servants to me rather than Allāh," but [instead, he would say], "Be pious scholars of the Lord because of what you have taught of the Scripture and because of what you have studied."

آل عمران 79

۞ لَتُبْلَوُنَّ فِىٓ أَمْوَٰلِكُمْ وَأَنفُسِكُمْ وَلَتَسْمَعُنَّ مِنَ ٱلَّذِينَ أُوتُوا۟ ٱلْكِتَـٰبَ مِن قَبْلِكُمْ وَمِنَ ٱلَّذِينَ أَشْرَكُوٓا۟ أَذًى كَثِيرًا ۚ وَإِن تَصْبِرُوا۟ وَتَتَّقُوا۟ فَإِنَّ ذَٰلِكَ مِنْ عَزْمِ ٱلْأُمُورِ

You will surely be tested in your possessions and in yourselves. And you will surely hear from those who were given the Scripture before you and from those who associate others with Allāh much abuse. But if you are patient and fear Allāh - indeed, that is of the matters [worthy] of resolve.

آل عمران 186

أَلَمْ تَرَ إِلَى ٱلَّذِينَ أُوتُوا۟ نَصِيبًا مِّنَ ٱلْكِتَـٰبِ يُؤْمِنُونَ بِٱلْجِبْتِ وَٱلطَّـٰغُوتِ وَيَقُولُونَ لِلَّذِينَ كَفَرُوا۟ هَـٰٓؤُلَآءِ أَهْدَىٰ مِنَ ٱلَّذِينَ ءَامَنُوا۟ سَبِيلًا

Have you not seen those who were given a portion of the Scripture, who believe in jibt [superstition] and ṭāghūt [false objects of worship] and say about the disbelievers, "These are better guided than the believers as to the way"?
