Definition and ordinary meaning

The abandonment of Islam, treated in classical legal schools through religious, civil and penal categories.

Historical setting

The term must be placed among Qurʾānic proclamation, early empire, later Sīra and Hadith, legal schools, theology and modern reform. A classical juristic definition is not automatically a verbatim transcript of the earliest community.

Meaning within the tradition

Within Islamic studies, Apostasy in Islam must be read according to the school, source and period that uses it. The same word may name a text, rite, institution or doctrine in more than one sense. This article therefore resists treating a later standardized definition as though it were present unchanged from the beginning.

Natural-philosophical and historical assessment

Law must be measured by natural justice, the true common good and the distinction between internal belief and external acts. A rule’s antiquity or religious authority within a system does not exempt it from rational moral judgement.

Catholic judgement and necessary distinctions

Catholic doctrine confesses one God in three consubstantial Persons, the Incarnation of the eternal Son, the true Cross and bodily Resurrection, and salvation by grace through Christ. Any Islamic term is therefore judged within a later system that contradicts the apostolic witness at its centre; shared vocabulary or inherited biblical material cannot authenticate that contradiction.

Primary texts and source control

Read the term first in the earliest available source and then in later school or institutional definitions. The following local routes keep documentary evidence separate from commentary.
