Sorry marriage and divorce should come under civil war. It determines inheritance, insurance etc. End of discussion
Please understand that even under the civil law, a marriage is a "contract". Even in the Western countries, there are civil laws of inheritance/insurance in marriages, but these civil laws become nullified if both parties go to the Notary and make a legal "contract" which specify other terms.
Muslim point of view is this that Islam gave this right of insurance and alimony in form of Haq Mehr.
Muslim also point out that girls have the right to put the conditions that 3 times Talaq does not apply, and women also have the right to talaq, and also to change the share in inheritance at time of Nikah.
But the present decision of the Supreme Court is directly in the violation of the marriage contract, which the Muslim boy made at the time of Nikah.
Also Supreme Court intervened in the personal Belief system. Supreme Court is compelling the Muslim man to indulge in fornication according to his belief.
Like I said before, state/court are no one to order a person to marry any girl, nor they are any one to tell a person to stay with some one.
This decision of supreme court will make the life of this Muslim couple like a Hell . Many complications are going to come out of it. The mother-in-law and other relatives of husband in the house will also see it as fornication under their roof.
For all this, religion has to be blamed. But the problem is this that even by introducing the civil laws, you are not going to come over these problems.
Muslim women should be educated and supported if the want to leave their religion or to marry a person who does not believe in 3 talaqs etc.
This thing is never going to end fine. Muslim women is hoping they get their happy life back. Supreme court also thinks it may help the poor Muslim women. But it is not going to happen unfortunately.
