Surah 52. At-Tur, Ayah 17

The Righteous will be in Bliss far beyond their merits: their sins and faults will be forgiven by the grace of Allah, which will save them from the penalties which they may have incurred from human frailty. It will be their own effort or striving which will win them Allah's grace: see verse 19 below. But the fruits will be greater than they could strictly have carned.
