25 Preface رَبُّكُم أَعلَمُ بِما في نُفوسِكُم ۚ إِن تَكونوا صالِحينَ فَإِنَّهُ كانَ لِلأَوّابينَ غَفورًاYusuf AliYour 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).1It is the heart, and its hidden and secret motives, by which we are judged: for God knows them all.
