Al Baqarah Ayah 111

وَقَالُواْ لَن يَدْخُلَ ٱلْجَنَّةَ إِلَّا مَن كَانَ هُودًا أَوْ نَصَـٰرَىٰ‌ۗ تِلْكَ أَمَانِيُّهُمْ‌ۗ قُلْ هَاتُواْ بُرْهَـٰنَكُمْ إِن كُنتُمْ صَـٰدِقِينَ ١١١ The Jews and Christians each claim that none will enter Paradise except those of their own faith. These are their desires. Reply, ?O Prophet,? “Show ?me? your proof if what you say is true.”
