مَّا جَعَلَ ٱللَّهُ لِرَجُلٍ مِّن قَلۡبَيۡنِ فِى جَوۡفِهِۦ ۚ وَمَا جَعَلَ أَزۡوَٰجَكُمُ ٱلَّٰٓـِٔى تُظَٰهِرُونَ مِنۡهُنَّ أُمَّهَٰتِكُمۡ ۚ وَمَا جَعَلَ أَدۡعِيَآءَكُمۡ أَبۡنَآءَكُمۡ ۚ ذَٰلِكُمۡ قَوۡلُكُم بِأَفۡوَٰهِكُمۡ ۖ وَٱللَّهُ يَقُولُ ٱلۡحَقَّ وَهُوَ يَهۡدِى ٱلسَّبِيلَ
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.<br/>
God has not placed two hearts inside any man: [this was revealed] in order to refute those disbelievers who said that they each had two hearts with which they could reason better than Muhammad's single mind; nor has He made your wives whom (read as allaa'ee, or allaa') you repudiate by zihaar (read tazzahharoona, or tuzaahiroona; the original taa' [of tatazaaharoona] has been assimilated with the zaa') - a man would say to his wife for example, 'You are for me as [untouchable as] my mother's back' - your mothers, in other words, [He has not made you wives] like [your] mothers, so that they are illicit [for conjugality] in that respect, [a practice] which in pre-Islamic times was considered a [valid form of] divorce. <br/><br/>An atonement with [necessary] conditions is necessary in such a case, as mentioned in soorat al-Mujaadila [Q. 58:2-3]. Nor has He made those whom you claim as [adopted] sons (ad'iyaa', the plural of da'iyy, which is one claimed as the son of one who is not his [biological] father) your sons, in reality. That is a mere utterance of your mouths, namely, [of] the Jews and the hypocrites. <br/><br/>When the Prophet may peace and salutation be upon him married Zaynab bt. Jahsh, who had been Zayd ibn Haaritha's wife, the adopted son of the Prophet may peace and salutation be upon him, they said, 'Muhammad married his son's wife!', and so God proved them liars in this. But God speaks the truth, in this [matter], and He guides to the way, the way of truth.
