The Repentance
In the Holy Quran:
إِنَّمَا التَّوْبَةُ عَلَى اللَّهِ لِلَّذِينَ يَعْمَلُونَ السُّوءَ بِجَهَالَةٍ ثُمَّ يَتُوبُونَ مِنْ قَرِيبٍ فَأُولَٰئِكَ يَتُوبُ اللَّهُ عَلَيْهِمْ ۗ وَكَانَ اللَّهُ عَلِيمًا حَكِيمًا {17}
But rather, ‘التَّوْبَةُ’ the repenting to Allah is only for those who do the evil (deed) out of ignorance, then they are repenting from shortly afterwards, so they are to whom Allah Turns (Mercifully) to them; and Allah was always most-Knowing, Wise [4:17]
