25رَبُّكُم أَعلَمُ بِما في نُفوسِكُم ۚ إِن تَكونوا صالِحينَ فَإِنَّهُ كانَ لِلأَوّابينَ غَفورًاShabbir AhmedYour Lord is best Aware of your psyche. If you fulfill the needs of others, you grow your own personality. If you turn to His Laws, He will protect your "Self" from deterioration. (Ghufarah = Helmet and armor).
