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
Allah hath not assigned unto any man two hearts within his body, nor hath He made your wives whom ye declare (to be your mothers) your mothers, nor hath He made those whom ye claim (to be your sons) your sons. This is but a saying of your mouths. But Allah saith the truth and He showeth the way.
Surah Al-Ahzaab(33:4)
