Al-Ahzab 33:4

Ma jaAAala Allahu lirajulin minqalbayni fee jawfihi wama jaAAala azwajakumu alla-eetuthahiroona minhunna ommahatikum wamajaAAala adAAiyaakum abnaakum thalikumqawlukum bi-afwahikum wallahu yaqoolu alhaqqawahuwa yahdee assabeel

Allāh has not made for a man two hearts in his interior. And He has not made your wives whom you declare unlawful your mothers. And He has not made your claimed [i.e., adopted] sons your [true] sons. That is [merely] your saying by your mouths, but Allāh says the truth, and He guides to the [right] way.

Allah has not made for any man two hearts in his chest cavity, nor did he make your wives whom you subjected to Zihār, your mothers, nor did he make your adopted sons your (real) sons. That is (merely) a word uttered by your mouths. And Allah says the truth and He shows the (right) way.
