Divine Decree — Al-Qada wal-Qadar

Divine decree (al-qada wal-qadar) occupies a lengthy section in al-Aqeedah al-Tahawiyyah, reflecting its central importance in Islamic theology and the historical controversies that have surrounded it. Al-Tahawi's treatment of this subject is among the most nuanced in his concise text, carefully navigating between two extremes that were active in his era and remain relevant to theological discussion today.

Al-Tahawi states: 'The root of divine decree — both its affirmation and the subtlety of its nature — is among the most veiled of Allah's secrets and the most closely guarded of His matters. There is no angel brought near nor prophet sent who can comprehend it fully. Delving into it to oppose it leads to deprivation and is a path to loss and deviation.' This opening statement is itself deeply instructive: al-Tahawi acknowledges the philosophical difficulty of the subject and counsels epistemological humility. Divine decree is not a mathematical problem to be solved but a divine mystery to be affirmed through revelation and trusted through faith.

The doctrine he affirms consists of four interconnected elements — the same four that later scholars would systematize: divine knowledge (that Allah knew all that would happen before it happened), divine inscription (that Allah wrote all events in the Preserved Tablet), divine will (that nothing happens except what He wills), and divine creation (that Allah is the Creator of all actions, including those of created beings). Together, these four elements constitute the Sunni understanding of divine sovereignty over all of existence.

The practical implication that al-Tahawi draws from this is that both extremes — the Jabriyyah (extreme determinists) and the Qadariyyah (those who denied divine foreknowledge and creation of human actions) — are in error. The Jabriyyah used divine decree as an excuse for sin: 'Allah decreed this, so I could not have done otherwise.' Al-Tahawi responds that this eliminates moral responsibility and contradicts the direct testimony of human consciousness, which experiences genuine choice even if that choice is within the framework of divine decree. The Qadariyyah, meanwhile, attempted to protect human responsibility by limiting divine sovereignty — a position that introduces into Islamic theology a domain of existence outside Allah's knowledge and will, which is both philosophically incoherent and theologically unacceptable.

Al-Tahawi also addresses the question of why Allah decrees good and evil, obedience and disobedience. His response reflects the Sunni doctrine that Allah is not questioned about what He does — 'He will not be asked about what He does, but they will be asked' (Quran 21:23) — and that human wisdom cannot fully comprehend divine wisdom. What humans can know is that Allah is just, that He does not wrong anyone, and that every decree of His is accompanied by wisdom even when that wisdom is hidden from us. The believer responds to this reality not with resentment but with trust: 'Allah — perfect is He — is more merciful to His servant than a mother is to her child.'
