Quran 7:153 — The Purgatory (Al-A'araf)

وَالَّذينَ عَمِلُوا السَّيِّـٔاتِ ثُمَّ تابوا مِن بَعدِها وَءامَنوا إِنَّ رَبَّكَ مِن بَعدِها لَغَفورٌ رَحيمٌ

As for those who committed sins, then repented thereafter and believed, your Lord—after this—is Forgiver, Most Merciful.

[7:152] Surely, those who idolized the calf have incurred wrath from their Lord, and humiliation in this life. We thus requite the innovators.

[7:154] When Moses' anger subsided, he picked up the tablets, containing guidance and mercy for those who reverence their Lord.
