Surah Al-Ahzaab, Verse 4
مَّا جَعَلَ ٱللَّهُ لِرَجُلٍۢ مِّن قَلْبَيْنِ فِى جَوْفِهِۦ ۚ وَمَا جَعَلَ أَزْوَٰجَكُمُ ٱلَّٰٓـِٔى تُظَٰهِرُونَ مِنْهُنَّ أُمَّهَٰتِكُمْ ۚ وَمَا جَعَلَ أَدْعِيَآءَكُمْ أَبْنَآءَكُمْ ۚ ذَٰلِكُمْ قَوْلُكُم بِأَفْوَٰهِكُمْ ۖ وَٱللَّهُ يَقُولُ ٱلْحَقَّ وَهُوَ يَهْدِى ٱلسَّبِيلَ
Translation — Sahih International
Allah has not made for a man two hearts in his interior. And He has not made your wives whom you declare unlawful your mothers. And he has not made your adopted sons your [true] sons. That is [merely] your saying by your mouths, but Allah says the truth, and He guides to the [right] way.
