In no way has Allah made to any man two hearts within the hollow (of his breast); and in no way has He made your spouses whom you (declare) as your mother's back (i.e., divorce by Dhihar, a pre-Islamic form of divorc) (truly) your mothers; and in no way has He made your adopted sons your sons (in fact). That (Literally: temptation; i.e., if the hypocrites had been asked to apostatize from Islam) is your saying, (the words) of your mouths; and Allah says the Truth, and He guides on the way.

Yusuf Ali

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.

Abul Ala Maududi(With tafsir)

(33:4) Allah has never put two hearts within one person's body;5 nor has He made your wives, whom you compare to your mothers' backs (to divorce them),6 your true mothers; nor has He made those whom you adopt as sons your own sons.7 These are only words that you utter with your mouths. But Allah proclaims the Truth and directs you to the Right Path.
