Quran Al-Baqarah 2:111
وَقَالُواْ لَن يَدۡخُلَ ٱلۡجَنَّةَ إِلَّا مَن كَانَ هُودًا أَوۡ نَصَٰرَىٰۗ تِلۡكَ أَمَانِيُّهُمۡۗ قُلۡ هَاتُواْ بُرۡهَٰنَكُمۡ إِن كُنتُمۡ صَٰدِقِينَ ١١١
Translation
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."
