وَقَالُوا۟ لَن يَدْخُلَ ٱلْجَنَّةَ إِلَّا مَن كَانَ هُودًا أَوْ نَصَـٰرَىٰ ۗ تِلْكَ أَمَانِيُّهُمْ ۗ قُلْ هَاتُوا۟ بُرْهَـٰنَكُمْ إِن كُنتُمْ صَـٰدِقِينَ

And they say, "None will enter Paradise except one who is a Jew or a Christian." That is [merely] their wishful thinking. Say, "Produce your proof, if you should be truthful."

Al-Baqarah 111

وَلَا تَكُونُوا۟ كَٱلَّذِينَ تَفَرَّقُوا۟ وَٱخْتَلَفُوا۟ مِنۢ بَعْدِ مَا جَآءَهُمُ ٱلْبَيِّنَـٰتُ ۚ وَأُو۟لَـٰٓئِكَ لَهُمْ عَذَابٌ عَظِيمٌ

And do not be like the ones who became divided and differed after the clear proofs had come to them. And those will have a great punishment

Ali 'Imran 105

كَيْفَ يَهْدِى ٱللَّهُ قَوْمًا كَفَرُوا۟ بَعْدَ إِيمَـٰنِهِمْ وَشَهِدُوٓا۟ أَنَّ ٱلرَّسُولَ حَقٌّ وَجَآءَهُمُ ٱلْبَيِّنَـٰتُ ۚ وَٱللَّهُ لَا يَهْدِى ٱلْقَوْمَ ٱلظَّـٰلِمِينَ

How shall Allāh guide a people who disbelieved after their belief and had witnessed that the Messenger is true and clear signs had come to them? And Allāh does not guide the wrongdoing people.

Ali 'Imran 86

يَـٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوا۟ لَا تَتَّخِذُوا۟ ٱلْكَـٰفِرِينَ أَوْلِيَآءَ مِن دُونِ ٱلْمُؤْمِنِينَ ۚ أَتُرِيدُونَ أَن تَجْعَلُوا۟ لِلَّهِ عَلَيْكُمْ سُلْطَـٰنًا مُّبِينًا

O you who have believed, do not take the disbelievers as allies instead of the believers. Do you wish to give Allāh against yourselves a clear case?

An-Nisa 144

قُلْ فَلِلَّهِ ٱلْحُجَّةُ ٱلْبَـٰلِغَةُ ۖ فَلَوْ شَآءَ لَهَدَىٰكُمْ أَجْمَعِينَ

Say, "With Allāh is the far-reaching [i.e., conclusive] argument. If He had willed, He would have guided you all."

Al-An'am 149
