Al-Baqara • EN-TAFSIR-IBN-ABBAS
﴿ وَقَالُوا۟ لَن يَدْخُلَ ٱلْجَنَّةَ إِلَّا مَن كَانَ هُودًا أَوْ نَصَٰرَىٰ ۗ تِلْكَ أَمَانِيُّهُمْ ۗ قُلْ هَاتُوا۟ بُرْهَٰنَكُمْ إِن كُنتُمْ صَٰدِقِينَ ﴾
“AND THEY claim, "None shall ever enter paradise unless he be a Jew" - or, "a Christian". Such are their wishful beliefs! Say: "Produce an evidence for what you are claiming, if what you say is true!"”
(And they say) i.e. the Jews: (None entereth Paradise unless he be a Jew) unless he dies as a Jew, allegedly (or a Christian) as the Christians also claimed. (These are their own desires) what they wish from Allah even though it is not in their Books. (Say) O Muhammad, to both parties: (Bring your proofs) from your own respective Books (if ye are truthful) in your claim.
