5:65

Al-Maaida 5:65

وَلَوْ أَنَّ أَهْلَ ٱلْكِتَٰبِ ءَامَنُوا۟ وَٱتَّقَوْا۟ لَكَفَّرْنَا عَنْهُمْ سَيِّـَٔاتِهِمْ وَلَأَدْخَلْنَٰهُمْ جَنَّٰتِ ٱلنَّعِيمِ

Wa law anna Ahlal Kitaabi aamanoo wattaqaw lakaffarnaa 'anhum saiyiaatihim wa la adkhalnaahu Jannaatin Na'eem

If only the People of the Book had believed and been righteous, We should indeed have blotted out their iniquities and admitted them to gardens of bliss.
