ٱدْعُوهُمْ لِـَٔابَآئِهِمْ هُوَ أَقْسَطُ عِندَ ٱللَّهِ ۚ فَإِن لَّمْ تَعْلَمُوٓا۟ ءَابَآءَهُمْ فَإِخْوَٰنُكُمْ فِى ٱلدِّينِ وَمَوَٰلِيكُمْ ۚ وَلَيْسَ عَلَيْكُمْ جُنَاحٌ فِيمَآ أَخْطَأْتُم بِهِۦ وَلَـٰكِن مَّا تَعَمَّدَتْ قُلُوبُكُمْ ۚ وَكَانَ ٱللَّهُ غَفُورًا رَّحِيمًا

Al-Ahzab — Ayah 5

The Combined Forces · الأحزاب · 33:5

Call them by (the name of) their (real) fathers; It is more equitable in the sight of Allah. And if you do not know their fathers, then they are your brothers in faith and your friends. There is no sin on you in the mistake you make, but in that which you do with intention of your heart; and Allah is Most-Forgiving, Very-Merciful.
