Quran 58, Al-Mujadila (She who disputes) ⓘ

58:2 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.

الَّذِينَ يُظَاهِرُونَ مِنْكُمْ مِنْ نِسَائِهِمْ مَا هُنَّ أُمَّهَاتِهِمْ إِنْ أُمَّهَاتُهُمْ إِلَّا اللَّائِي وَلَدْنَهُمْ وَإِنَّهُمْ لَيَقُولُونَ مُنْكَرًا مِنَ الْقَوْلِ وَزُورًا وَإِنَّ اللَّهَ لَعَفُوٌّ غَفُورٌ
