5:65
وَلَوْ أَنَّ أَهْلَ ٱلْكِتَـٰبِ ءَامَنُوا۟ وَٱتَّقَوْا۟ لَكَفَّرْنَا عَنْهُمْ سَيِّـَٔاتِهِمْ وَلَأَدْخَلْنَـٰهُمْ جَنَّـٰتِ ٱلنَّعِيمِ
walaw anna ahla l-kitābi āmanū wa-ittaqaw lakaffarnā ʿanhum sayyiātihim wala-adkhalnāhum jannāti l-naʿīmi
If only the People of the Book would believe and be mindful of God, We would take away their sins and bring them into the Gardens of Delight.
And if only the people of the Scripture (Jews and Christians) had believed (in Muhammad صلى الله عليه وسلم) and warded off evil (sin, ascribing partners to Allâh) and had become Al-Muttaqûn (the pious - See V.2:2) We would indeed have expiated from them their sins and admitted them to Gardens of pleasure (in Paradise).
