Concept:Islam introduced specific legal rights for women, with inheritance being a major welfare reform that was absent in pre-Islamic Arabia.
Explanation:Before the advent of Islam, women in Arabia were not allowed to inherit property or own wealth.
Islam changed this by introducing clear inheritance laws that gave women a fixed and protected share of a deceased person's estate.
The Qur'an specifies definite portions for daughters, wives, mothers, and sisters.
For example, a daughter receives half of a son's share from the same father, yet her share is hers by right, not by favour.
These provisions improved the social and economic standing of women in society.
Meanwhile, marriage, family planning, and women seclusion were customs already known among various communities before Islam.
Hence, the introduction of the right to inheritance is the unique contribution of Islam to the welfare of women.
