Repentance and seeking forgiveness (istighfār)

ٱلَّذِينَ يَقُولُونَ رَبَّنَآ إِنَّنَآ ءَامَنَّا فَٱغْفِرْ لَنَا ذُنُوبَنَا وَقِنَا عَذَابَ ٱلنَّارِ

Those who say, "Our Lord, indeed we have believed, so forgive us our sins and protect us from the punishment of the Fire,"

وَمَا كَانَ ٱللَّهُ لِيُعَذِّبَهُمْ وَأَنتَ فِيهِمْ ۚ وَمَا كَانَ ٱللَّهُ مُعَذِّبَهُمْ وَهُمْ يَسْتَغْفِرُونَ

But Allāh would not punish them while you, [O Muḥammad], are among them, and Allāh would not punish them while they seek forgiveness.
