Al-Tahsin wa'l-Taqbih (التَّحسِين وَالتَّقبِيح — making beautiful and making ugly; in kalam (Islamic theology), this refers to the central debate about whether human reason can independently determine what is morally good (hasan) and morally ugly (qabih) without revelation's guidance, or whether goodness and ugliness are determined solely by divine command) is among the most fundamental debates in Islamic moral theology. The Mu'tazili position (*tahsin wa taqbih 'aqliyan* — rational moral judgment): human reason can, and must, determine that justice is good and oppression is evil, that gratitude is beautiful and ingratitude is ugly — independently of whether revelation commands them. If Allah commanded oppression, it would still be ugly. The Ash'ari response: goodness and ugliness are not independent properties that reason discovers but divine designations. What Allah commands is good by the fact of His commanding it; what He prohibits is ugly by the fact of His prohibiting it. The Maturidi middle: reason can recognize some moral qualities (gratitude to the benefactor, fairness) but cannot fully specify obligations without revelation. The stakes: if Mu'tazila are right, Allah is bound by rational moral criteria He did not create — limiting divine freedom. If Ash'aris are right, morality is purely conventional — making divine arbitrariness possible. The debate has never been fully resolved in Islamic thought, though the Ash'ari position became dominant in Sunni kalam. Ismaili philosophy: the Imam's authority in moral matters is not divine arbitrariness but the authoritative interpretation of the eternal moral order grounded in divine wisdom — transcending the Mu'tazili/Ash'ari dichotomy.

The Mu’tazili and Ash’ari Positions

Mu’tazila: The Mu’tazili insistence on rational moral judgment (tahsin ‘aqli) was not merely philosophical but theological: if reason cannot determine justice and oppression are independently real, then divine justice itself becomes unintelligible. The famous Mu’tazili argument: ‘If the Prophet commands us to oppress the innocent, would that be good?’ — to which the Mu’tazili answers no, demonstrating that goodness is not merely what is commanded.

Ash’ari: The Ash’ari (and Hanbali) response was equally principled: placing rational criteria above divine command is shirk of reason — a subtle idolatry that makes human rational judgment the measure of divine action. ‘He is not questioned about what He does, but they will be questioned.’ (21:23) — divine sovereignty is absolute.

The Ismaili Position

Imam as moral authority: Ismaili philosophy approaches this debate from a different angle: the question is not whether reason or revelation is the primary moral guide, but where the living authority for moral interpretation resides. The Imam — who carries the full ‘ilm of the prophetic message and the cosmic moral order — is the authoritative interpreter of what is hasan and qabih in each age. This transcends the Mu’tazili/Ash’ari dichotomy: the Imam’s judgment is neither purely rational nor purely conventional but the living instantiation of divine wisdom in the world.
