Tawbah

Tawbah is repentance, and the word means a turning. What is distinctive in the Qur'anic usage is that the same root is used of both parties: the servant turns to God, and God is al-Tawwab, the one who turns toward, who relents and accepts. The relation is stated at 9:118, where God turns to those who had failed "so that they might turn", divine acceptance both precedes and answers the human movement, a structure the theologians used when discussing the relation of grace and act.

The conditions are set out consistently by jurists and moralists: regret for what was done, desisting from it, firm resolve not to return, and, where another person has been wronged, restitution or the seeking of their pardon, since wrongs against people are not held to be discharged by God's forgiveness of the offence against himself. The door is described as open until death is actually upon a person (4:17-18) or, in a widely reported hadith, until the sun rises in the west.

Islam has no institution of confession to an intermediary, and no absolution pronounced by another. Tawbah is direct, and the tradition actively discourages publicising one's own sins, treating concealment as the ordinary rule and disclosure as itself a fault. The Qur'an couples the demand with repeated assurance, "do not despair of the mercy of God; God forgives all sins" (39:53), and the ninth chapter is named al-Tawbah, Repentance. Jewish teshuvah and Christian penitence share the underlying structure of turning and are treated comparatively in the entry on Repentance; the differences lie less in the requirement than in what mediates it.

Tawbah's practical mechanics were never seriously disputed within Islamic scholarship, but a related and much sharper controversy arose in the earliest centuries of Islam over what a grave sin, committed and not yet repented of, does to a person's standing as a believer, and the argument shaped the formation of Sunni theology itself.

The Khawarij, emerging from a faction that had broken with Ali after the arbitration at Siffin in 657, held that a Muslim who commits a grave sin (a kabira) thereby becomes an unbeliever outright. The Mu'tazila rejected full unbelief but also rejected the Khawarij's opposite, that the grave sinner remains simply a believer; they proposed an intermediate category, al-manzila bayna al-manzilatayn, "the position between the two positions," holding that an unrepentant grave sinner is neither a believer nor an unbeliever, a status this school made one of its five foundational principles.

The Murji'a, by contrast, held that judgment on such a person should be postponed (irja) to God alone, and that faith consists essentially in belief and confession rather than in works, so a grave sinner remains fully a believer whose sin does not touch the reality of his faith. This position fed into what became the mainstream Sunni Ash'ari and Maturidi settlement: that grave sin does not expel a person from Islam, that judgment belongs to God, and that sincere tawbah, when it occurs, is efficacious regardless of which of these positions on unrepented sin one otherwise holds.
