According to search-discovered classical Islamic scholarship, the Iddah (العدة) is a mandatory waiting period a woman observes after the termination of her marriage through divorce or the death of her husband. This is not merely a waiting time but a crucial component of Islamic family law with profound wisdom. Classical jurists, interpreting key Quranic verses like 65:6 and 2:228, explain its purposes: to ascertain pregnancy, thus preserving the purity of lineage; to provide an opportunity for reconciliation in cases of revocable divorce; and to serve as a period of mourning and respect for a deceased husband. Al-Qurtubi, in his legal tafsir, emphasizes the rights of the woman during this period, particularly her right to lodging and maintenance as mandated in Surah At-Talaq. The linguistic root in Arabic, meaning 'to count,' signifies that this is a divinely appointed, calculated period of worship and transition. Contemporary scholars affirm that these classical rulings continue to provide a framework for justice, dignity, and social stability in modern contexts, ensuring the woman is protected during a vulnerable time.
