Sura al-Baqara 2:111

وَقَالُوا۟ لَن يَدْخُلَ ٱلْجَنَّةَ إِلَّا مَن كَانَ هُودًا أَوْ نَصَٰرَىٰ تِلْكَ أَمَانِيُّهُمْ قُلْ هَاتُوا۟ بُرْهَٰنَكُمْ إِن كُنتُمْ صَٰدِقِينَ

wa-qālū lan yadkhula l-jannata illā man kāna hūdan aw naṣārā tilka amānīyuhum qul hātū burhānakum in kuntum ṣādiqīna

And they say: "None shall enter Paradise unless he be a Jew or a Christian." Those are their (vain) desires. Say: "Produce your proof if ye are truthful."
