The Quran

لِيَجزِيَ اللَّهُ الصّادِقينَ بِصِدقِهِم وَيُعَذِّبَ المُنافِقينَ إِن شاءَ أَو يَتوبَ عَلَيهِم ۚ إِنَّ اللَّهَ كانَ غَفورًا رَحيمًا

Ali Unal

In consequence, God will reward the truthful ones for having been true to their covenant, and punish the hypocrites if He wills, or turn to them in lenience and accept their repentance (if they repent). Surely God is All-Forgiving, All-Compassionate.¹

The verse subtly implies that God’s punishment depends on His Will: if He so wills, He punishes those who deserve it, but He may pardon them as well. But if any of His servants turn to Him with true repentance, He accepts their repentance. The conclusion of the verse mentioning God as All-Forgiving, All-Compassionate emphasizes His forgiveness and, therefore, encourages His sinful servants and even the hypocrites to turn to Him in true faith and repentance and mend their ways with the hope of being forgiven.
