The sacred law of Islām is a complete and chaste system of life. The proper functioning of human race depends on the proper maintenance of marital relationship. Islām has focused attention on family issues most exhaustively. By a careful analysis of the holy Qurʾān, we notice that commercial contracts like sale, partnership, hiring and so on are though among the most important socio-economic matters, the holy Qurʾān has restricted itself to setting down their basic principles, and the bye-laws are rarely ever touched upon.
In matters of marriage and divorce, on the other hand, not only fundamental principles have been laid down, but their detailed laws have also been directly revealed by Allāh and entrenched in the holy Qurʾān. These laws are scattered in various chapters. Sūrah Talāq, specifically deals with ‘divorce’, ‘the period of ʿiddah’ and so on. Thus, according to some narratives, this sūrah is also called Sūrah an-Nisāʾ as-Sughrā or the short Sūrah an-Nisāʾ (Qurtubī).
