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

“If the followers of the Bible would but attain to [true] faith and God-consciousness, We should indeed efface their [previous] bad deeds, and indeed bring them into gardens of bliss;”

But had the People of the Scripture believed in Muhammad (s) and feared unbelief We would have absolved them of their evil deeds and We would admitted them to Gardens of Bliss.
