Explanation:

- The Dissolution of Muslim Marriage Act, 1939 was enacted in India to provide Muslim women grounds for divorce.

- Before this Act, under the Hanafi school, getting a divorce was extremely difficult for women, as the grounds were very limited.

- The Act drew inspiration from the Maliki school of Muslim law, which is more progressive and allows more reasons for women to seek divorce.

- The Act incorporates the broader and more liberal grounds of divorce found in the Maliki school, not just Hanafi.

- Shafai and Zaidi schools were not the primary basis for the Act.
