Making Laws Against The Permissions Granted By Allah
In Pakistan the State already has a law that a husband has to take permission of the first wife before marrying a second time. This was to prevent injustice to his first wife and children
Ahmad the permission is granted in order to render good in the society, as is clear from the context. The fundamental thing that God is after, is the spread of good while still maintaining justice. If the society notices that the permission is being misused by people and is in fact having a negative effect in a particular society then they can place restrictions as needed. Umar Ibn Al-Khattaab RA suspended the punishment of cutting hands of the thieves in the year of famine. This was not about changing the law of God, but in fact implementing the law of God in a manner where it’s spirit is completely fulfilled even if it can’t be fulfilled in the letter.
