Qur'an 2:111

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 one who is a Jew or a Christian." That is [merely] their wishful thinking. Say, "Produce your proof, if you should be truthful."”
