Surat Al-'Aĥzāb - سورة الأحزاب

مَّا جَعَلَ اللَّهُ لِرَجُلٍ مِّن قَلْبَيْنِ فِي جَوْفِهِ ۚ وَمَا جَعَلَ أَزْوَاجَكُمُ اللَّائِي تُظَاهِرُونَ مِنْهُنَّ أُمَّهَاتِكُمْ ۚ وَمَا جَعَلَ أَدْعِيَاءَكُمْ أَبْنَاءَكُمْ ۚ ذَٰلِكُمْ قَوْلُكُم بِأَفْوَاهِكُمْ ۖ وَاللَّهُ يَقُولُ الْحَقَّ وَهُوَ يَهْدِي السَّبِيلَ

Muhsin Khan: Allah has not put for any man two hearts inside his body. Neither has He made your wives whom you declare to be like your mothers' backs, your real mothers. [AzZihar is the saying of a husband to his wife, "You are to me like the back of my mother" i.e. You are unlawful for me to approach.], nor has He made your adopted sons your real sons. That is but your saying with your mouths. But Allah says the truth, and He guides to the (Right) Way.
