رَّبُّكُمۡ أَعۡلَمُ بِمَا فِي نُفُوسِكُمۡۚ إِن تَكُونُواْ صَٰلِحِينَ فَإِنَّهُۥ كَانَ لِلۡأَوَّٰبِينَ غَفُورٗا ٢٥
Your Lord is most knowing of what is within yourselves. If you should be righteous [in intention] - then indeed He is ever, to the often returning [to Him], Forgiving.1
Translation: Saheeh International (English)
1 For those who intend righteousness, hastening to repent from sins and errors committed through human weakness, Allāh (subḥānahu wa taʿālā) promises forgiveness.
Each word's meaning and sound
Your Lord - O People - knows best what is within you of the sincere devotion to Him in worship, acts of goodness and being dutiful to parents. If the intention in your acts of worship, treatment of your parents and other acts is righteous, then He, may He be glorified, is Forgiving towards those who frequently turn to Him in repentance. If anyone repents from his prior failure to be dutiful to his Lord or to his parents, Allah will forgive him.
