And if only the People of the Scripture had believed and feared (5:65)

﴿وَلَوْ أَنَّ أَهْلَ الْكِتَابِ آمَنُوا وَاتَّقَوْا لَكَفَّرْنَا عَنْهُمْ سَيِّئَاتِهِمْ وَلَأَدْخَلْنَاهُمْ جَنَّاتِ النَّعِيمِ﴾
[ المائدة: 65]

5:65 And if only the People of the Scripture had believed and feared Allah, We would have removed from them their misdeeds and admitted them to Gardens of Pleasure.

If the Jews and the Christians accepted what was brought by Muhammad ( peace be upon him ) and were mindful of Allah by leaving sins, I would have forgiven the sins they committed, even if they were many, and I would have entered them on the Day of Judgement into gardens of delight, in which they would enjoy delights that will never end.

And if only the people of the Scripture (Jews and Christians) had believed (in Muhammad SAW) and warded off evil (sin, ascribing partners to Allah) and had become Al-Muttaqun (the pious - see V. 2:2) We would indeed have blotted out their sins and admitted them to Gardens of pleasure (in Paradise).
