Surah Al-Isra' (The Night Journey), Verse 25

رَبُّكُمْ اَعْلَمُ بِمَا فِیْ نُفُوْسِكُمْ اِنْ تَكُوْنُوْا صٰلِحِیْنَ فَاِنَّهٗ كَانَ لِلْاَوَّابِیْنَ غَفُوْرًا ۟

Rabbukum a'lamu bimaa fee nufoosikum; in takoonoo saaliheena fa innahoo kaana lil awwaabeena Ghafoooraa

“Your Lord knoweth best what is in your hearts: If ye do deeds of righteousness, verily He is Most Forgiving to those who turn to Him again and again (in true penitence).”
