conditional redemption

وَلَوْ أَنَّ أَهْلَ ٱلْكِتَـٰبِ ءَامَنُوا۟ وَٱتَّقَوْا۟ لَكَفَّرْنَا عَنْهُمْ سَيِّـَٔاتِهِمْ وَلَأَدْخَلْنَـٰهُمْ جَنَّـٰتِ ٱلنَّعِيمِ

And if only the People of the Scripture had believed and feared Allāh, We would have removed from them their misdeeds and admitted them to Gardens of Pleasure.
