Brief Explanation
Benefits: … Disobedience is extremely bad in every circumstance, and to make a vow (nadhar) and then commit disobedience is even more reprehensible. No evil can become a virtue merely by making a vow; therefore, it is not permissible to use the excuse of a vow to disobey Allah Ta‘ala—rather, it will be an even greater sin. Thus, a vow to commit disobedience should not be fulfilled; instead, its expiation (kaffarah) should be given.
