Surah Al-Ahzab (The Enemy Alliance), Verse 4

مَا جَعَلَ اللّٰهُ لِرَجُلٍ مِّنْ قَلْبَیْنِ فِیْ جَوْفِهٖ وَمَا جَعَلَ اَزْوَاجَكُمُ الّٰٓـِٔیْ تُظٰهِرُوْنَ مِنْهُنَّ اُمَّهٰتِكُمْ وَمَا جَعَلَ اَدْعِیَآءَكُمْ اَبْنَآءَكُمْ ذٰلِكُمْ قَوْلُكُمْ بِاَفْوَاهِكُمْ وَاللّٰهُ یَقُوْلُ الْحَقَّ وَهُوَ یَهْدِی السَّبِیْلَ ۟

Maa ja'alal laahu lirajulim min qalbaini fee jawfih; wa maa ja'ala azwaajakumul laaa'ee tuzaahiroona minhunna ummahaatikum; wa maa ja'ala ad'iyaaa'akum abnaaa'akum; zaalikum qawlukum bi afwaa hikum wallaahu yaqoolul haqqa wa Huwa yahdis sabeel

“Allah has not made for any man two hearts in his (one) body: nor has He made your wives whom ye divorce by Zihar your mothers: nor has He made your adopted sons your sons. Such is (only) your (manner of) speech by your mouths. But Allah tells (you) the Truth, and He shows the (right) Way.”
