Introduction: The Foundations of Islamic Governance

Al-Siyasah al-Shar'iyyah fi Islah al-Ra'i wa al-Ra'iyyah (Governance According to Shariah in Reforming the Ruler and the Ruled) is one of the most influential works on Islamic political theory and the obligations of those in authority. Its author, Taqi al-Din Ahmad ibn Taymiyyah (661–728 AH / 1263–1328 CE), wrote it during a period of significant political turbulence — the aftermath of the Mongol invasions, the Crusader presence in the Levant, and the political fragmentation of the Islamic world. The work addresses both the theoretical foundations of just governance and the practical obligations of rulers and state officials in applying Islamic law.

Ibn Taymiyyah was one of the most influential and controversial scholars of the Hanbali school. His approach to Islamic governance was shaped by his conviction that Islamic law provides a complete and practical framework for political life, and that the failures of Muslim governance in his era were not due to any inadequacy in Islam but to the failure of rulers and scholars to understand and implement its teachings correctly.

The Central Verse: Two Trusts

Ibn Taymiyyah bases his entire discussion of governance on the Quranic verse (4:58): 'Indeed, Allah commands you to render trusts to their owners, and when you judge between people to judge with justice.' He identifies two principal duties of governance flowing from this verse: the discharge of trusts (ada' al-amanat) and the judgment with justice (al-hukm bil-adl). Everything else in the work is an elaboration of what these two obligations require in practice.

The amanat (trusts) referred to in the verse include, for a ruler, the proper discharge of all governmental responsibilities: collecting taxes justly, distributing resources equitably, appointing qualified officials, maintaining the army, administering justice, protecting the community from enemies, and ensuring the performance of the religious obligations. A ruler who fails in any of these responsibilities has betrayed a trust that God has placed in his hands.

The Relationship Between Religion and Politics

A foundational argument in Al-Siyasah al-Shar'iyyah is that religion and political authority are mutually dependent. Ibn Taymiyyah quotes the famous saying attributed to various early Muslim thinkers: 'Religion without political authority will be disrupted, and political authority without religion will be tyranny.' This integration of religious and political function distinguishes the Islamic theory of governance from both theocracy (where religion displaces politics) and secularism (where politics displaces religion).

Ibn Taymiyyah argues that the state's proper function is to make it possible for people to fulfill their religious obligations in peace and security. Justice is not merely a political virtue — it is a religious one. A just non-Muslim ruler who maintains order and protects people's rights is superior, from the perspective of this world's welfare, to an unjust Muslim ruler who claims religious authority while violating the rights of his subjects.
