Prohibition of "dhihar" divorce and adoption in Islam

God has not provided two hearts in the breast of a man, nor made your wives, whom you pronounce "mothers" (in order to divorce them), your real mothers, nor has He made your adopted sons your real sons. This is only what your lips pronounce. God says what is just, and shows the right way.

Call them by the names of their fathers. This is the right course in the sight of God. If you do not know their fathers, they are then your brothers in religion and your friends. It will not be a sin if you make a mistake, unless you do so intentionally; for God is forgiving and kind.
