Surah Al-Mujadila, Verse 2

ٱلَّذِينَ يُظَٰهِرُونَ مِنكُم مِّن نِّسَآئِهِم مَّا هُنَّ أُمَّهَٰتِهِمۡۖ إِنۡ أُمَّهَٰتُهُمۡ إِلَّا ٱلَّٰٓـِٔي وَلَدۡنَهُمۡۚ وَإِنَّهُمۡ لَيَقُولُونَ مُنكَرٗا مِّنَ ٱلۡقَوۡلِ وَزُورٗاۚ وَإِنَّ ٱللَّهَ لَعَفُوٌّ غَفُورٞ٢

alladhīna yuẓāhirūna minkum min nisāihim mā hunna ummahātihim in ummahātuhum illā allāī waladnahum wa-innahum layaqūlūna munkaran mina l-qawli wazūran wa-inna l-laha laʿafuwwun ghafūrun

Those who pronounce ẓihār among you [to separate] from their wives - they are not [consequently] their mothers. Their mothers are none but those who gave birth to them. And indeed, they are saying an objectionable statement and a falsehood. But indeed, Allāh is Pardoning and Forgiving.
