﴿ 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.”

(Allah hath not assigned unto any man two hearts within his body�) [33:4]. This verse was revealed about Jamil ibn Ma'mar al-Fihri who was a sensible man who memorised whatever he heard. The Quraysh said: �He could not have memorised all these things unless he had two hearts�. Labib used to say: �I have two hearts and my perception by means of either one of them is better than the perception of Muhammad�. When the Battle of Badr took place and the idolaters were defeated, Abu Sufyan met Jamil ibn Ma'mar, who had accompanied the idolaters. Jamil was wearing one shoe and holding the other shoe in his hand. Abu Sufyan asked him: �What is the state of people?� He said: �They were defeated�. Abu Sufyan asked him again: �But why are you wearing one shoe and holding the other in your hand?� Jamil said: �I thought I was wearing both shoes�. On that day, people knew that he would not have forgotten his shoe in his hand if he really had two hearts. (hath He made those whom ye claim (to be your sons) your sons) [33:4]. This verse was revealed about Zayd ibn Harithah. He was a slave of the Messenger of Allah, Allah bless him and give him peace, but he freed him and adopted him before he was sent as a Prophet. When the Prophet, Allah bless him and give him peace, married Zaynab bint Jahsh, who was the divorcee of Zayd ibn Harithah, the Jews and hypocrites said: �Muhammad has married the wife of his son while forbidding people from doing the same!� And so Allah, exalted is He, revealed this verse. Sa'id ibn Muhammad ibn Ahmad ibn Nu'aym al-Ishkabi informed us> al-Hasan ibn Ahmad ibn Muhammad ibn 'Ali ibn Makhlid> Muhammad ibn Ishaq al-Thaqafi> Qutaybah ibn Sa'id> Ya'qub ibn 'Abd al-Rahman> Musa ibn 'Uqbah> Salim> 'Abd Allah ibn 'Umar who used to say: �We did not use to call Zayd ibn Harithah with any other name except Zayd ibn Muhammad until the Qur'an revealed (Proclaim their real parentage. That will be more equitable in the sight of Allah) [33:5]�. This was narrated by Bukhari> Mu'alla ibn Asad> 'Abd al-'Aziz ibn al-Mukhtar> Musa ibn 'Uqbah.
