Quran

 2:111

وَقَالُوا لَنْ يَدْخُلَ الْجَنَّةَ إِلَّا مَنْ كَانَ هُودًا أَوْ نَصَارَىٰ ۗ تِلْكَ أَمَانِيُّهُمْ ۗ قُلْ هَاتُوا بُرْهَانَكُمْ إِنْ كُنْتُمْ صَادِقِينَ ﴿١١١﴾

111. And they say, “None will enter Heaven unless he is a Jew or a Christian.” These are their wishes. Say, “Produce your proof, if you are truthful.”
