Marriage is a (mithaq) solemn covenant or agreement between husband and wife

The Free Consent of the Parties The Quran [4:21] refers to marriage as a mithaq, i.e. a solemn covenant or agreement between husband and wife, and enjoins that it be put down in writing. Since no agreement can be reached between the parties unless they give their consent to it, marriage can be contracted only with the free consent of the two parties.
