﴿ 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 ﴾

“NEVER has God endowed any man with two hearts in one body: and [just as] He has never made your wives whom you may have declared to be “as unlawful to you as your mothers’ bodies” [truly] your mothers, so, too, has He never made your adopted sons [truly] your sons: these are but [figures of] speech uttered by your mouths - whereas God speaks the [absolute] truth: and it is He alone who can show [you] the right path.”
