Surah Al-Baqarah, Verse 111

وَقَالُواْ لَن يَدۡخُلَ ٱلۡجَنَّةَ إِلَّا مَن كَانَ هُودًا أَوۡ نَصَٰرَىٰۗ تِلۡكَ أَمَانِيُّهُمۡۗ قُلۡ هَاتُواْ بُرۡهَٰنَكُمۡ إِن كُنتُمۡ صَٰدِقِينَ١١١

waqālū lan yadkhula l-janata illā man kāna hūdan aw naṣārā til'ka amāniyyuhum qul hātū bur'hānakum in kuntum ṣādiqīna

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."
