Surah Al-Mujadila · Ayah 2

ٱلَّذِينَ يُظَٰهِرُونَ مِنكُم مِّن نِّسَآئِهِم مَّا هُنَّ أُمَّهَٰتِهِمْ ۖ إِنْ أُمَّهَٰتُهُمْ إِلَّا ٱلَّٰٓـِٔى وَلَدْنَهُمْ ۚ وَإِنَّهُمْ لَيَقُولُونَ مُنكَرًۭا مِّنَ ٱلْقَوْلِ وَزُورًۭا ۚ وَإِنَّ ٱللَّهَ لَعَفُوٌّ غَفُورٌۭ

Allazeena yuzaahiroona minkum min nisaaa'ihim maa hunnaa ummahaatihim in ummahaatuhum illal laaa'ee waladnahum; wa innaahum la yaqooloona munkaram minal qawli wa zooraa; wa innal laaha la'afuwwun ghafoor

Those who pronounce thihar 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, Allah is Pardoning and Forgiving.
