33:5
ٱدۡعُوهُمۡ لِـَٔابَاۤىِٕهِمۡ هُوَ أَقۡسَطُ عِندَ ٱللَّهِۚ فَإِن لَّمۡ تَعۡلَمُوۤا۟ ءَابَاۤءَهُمۡ فَإِخۡوَ ٰنُكُمۡ فِی ٱلدِّینِ وَمَوَ ٰلِیكُمۡۚ وَلَیۡسَ عَلَیۡكُمۡ جُنَاحࣱ فِیمَاۤ أَخۡطَأۡتُم بِهِۦ وَلَـٰكِن مَّا تَعَمَّدَتۡ قُلُوبُكُمۡۚ وَكَانَ ٱللَّهُ غَفُورࣰا رَّحِیمًا
Proclaim their real parentage. That will be more equitable in the sight of Allah. And if ye know not their fathers, then (they are) your brethren in the faith, and your clients. And there is no sin for you in the mistakes that ye make unintentionally, but what your hearts purpose (that will be a sin for you). Allah is ever Forgiving, Merciful.
