Surah 2 : Ayah 111

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 a Jew or a Christian.” That is their wishful thinking. Say, “Produce your proof, if you are truthful.”
