Surah Al-Ahzab Verse 5 - English Translation by A. J. Arberry
Surah Al-Ahzabٱدۡعُوهُمۡ لِأٓبَآئِهِمۡ هُوَ أَقۡسَطُ عِندَ ٱللَّهِۚ فَإِن لَّمۡ تَعۡلَمُوٓاْ ءَابَآءَهُمۡ فَإِخۡوَٰنُكُمۡ فِي ٱلدِّينِ وَمَوَٰلِيكُمۡۚ وَلَيۡسَ عَلَيۡكُمۡ جُنَاحٞ فِيمَآ أَخۡطَأۡتُم بِهِۦ وَلَٰكِن مَّا تَعَمَّدَتۡ قُلُوبُكُمۡۚ وَكَانَ ٱللَّهُ غَفُورٗا رَّحِيمًا
Call them after their true fathers; that is more equitable in the sight of God. If you know not who their fathers were, then they are your brothers in religion, and your clients. There is no fault in you if you make mistakes, but only in what your hearts premeditate. God is All-forgiving, All-compassionate
