Al Ahzab, 5 Ayah
33:5
ٱدۡعُوهُمۡ 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 ٥
Ad`ūhum Li'abā'ihim Huwa 'Aqsaţu `Inda Al-Lahi ۚ Fa'in Lam Ta`lamū 'Ābā'ahum Fa'ikhwānukum Fī Ad-Dīni Wa Mawālīkum ۚ Wa Laysa `Alaykum Junāĥun Fīmā 'Akhţa'tum Bihi Wa Lakin Mā Ta`ammadat Qulūbukum ۚ Wa Kāna Al-Lahu Ghafūrāan Raĥīmāan
Call them by [the names of] their fathers; it is more just in the sight of Allah . But if you do not know their fathers - then they are [still] your brothers in religion and those entrusted to you. And there is no blame upon you for that in which you have erred but [only for] what your hearts intended. And ever is Allah Forgiving and Merciful.
