The apex court by 3:2 verdict held that the Triple Talaq is against the basic tenets of Quran.
Some Muslim institutions have said that while triple talaq is wrong, the law should be reviewed by the community itself.
The Supreme Court set aside the practice of divorce through triple talaq among Muslims, saying the practice was void, illegal and unconstitutional.
The panel, which consisted of five judges-Chief Justice Jagdish Singh Khehar, Justice Kurian Joseph, Justice Rohinton Fali Nariman, Justice Uday Umesh Lalit, and Justice S Abdul Nazeer decided on the constitutional validity of triple talaq.
The then Attorney General Mukul Rohatgi had presented the practice of instant divorce as a violation of a woman's right to be treated equally.
Madhya Pradesh Chief Minister Shivraj Singh Chouhan hailed the Supreme Court's ruling on triple talaq and urged the central government to bring a legislation in the matter soon. He also said, that the judgment grants equality to Muslim women and is a powerful measure for women empowerment.
Triple talaq is legal for Muslims according to the constitution, but several Muslim women who have been divorced, including by Skype and on WhatsApp, had challenged the 1400-year-old practice.
Asked if the government will come out with a new law, he said, "As of now, there is now need of introducing a new law".
Zakia Soman (Co-founder of the Indian Muslim Women's Movement): "It's a very happy day for us".
The top court had heard from stake holding parties such as the All India Muslim Personal Law Board (AIMPLB) and the Centre during the hearings. Instant talaq, or "talaq-e-biddat", is banned in 22 Muslim-majority countries, including Pakistan, for being sinful and arbitrary.
In a reaction to the verdict, Shayara Bano, the main petitioner, said "I welcome and support the judgment". A survey in India, conducted in 2015 by the Muslim women's activist group Bharatiya Muslim Mahila Andolan, indicated that one in 11 Muslim women were subjected to the triple talaq.
Dubbing it as a "path-breaking judgement", Rohatgi said the stand of the government was "completely vindicated" and the judgement has restored the dignity of the Muslim women who can now march to progress like other citizens of the country.
