Quran 5:65 from Surah Al-Maaida on Divine Marvels.
وَلَوۡ أَنَّ أَهۡلَ ٱلۡكِتَٰبِ ءَامَنُواْ وَٱتَّقَوۡاْ لَكَفَّرۡنَا عَنۡهُمۡ سَيِّـَٔاتِهِمۡ وَلَأَدۡخَلۡنَٰهُمۡ جَنَّٰتِ ٱلنَّعِيمِ
English translation: And if that (the) People (of) the Book (had) believed and feared (Allah) surely We (would have) removed from them their evil (deeds) and surely We (would have) admitted them [to] Gardens (of) Bliss
Transliteration: walaw anna ahla al-kitabi amanu wa-ittaqaw lakaffarna anhum sayyiatihim wala-adkhalnahum jannati al-na'imi
