Major legal concerns are distributed across several sūrahs, but each forms a connected area of instruction:
Prayer and almsgiving: fundamental commands with Prophetic explanation.
Fasting: al-Baqarah.
Pilgrimage: al-Baqarah and al-Ḥajj.
Jihād: al-Baqarah, al-Anfāl, and other passages.
Legal boundaries: al-Mā’idah and al-Nūr.
Inheritance: al-Nisāʾ.
Marriage and divorce: al-Baqarah, al-Nisāʾ, and al-Ṭalāq.
This is an interpretive map, not just a reference list. A subject must be traced through its relevant passages while preserving each passage’s wording and context.
