The Koran speaks of death, the end of the world, and resurrection more than any other major scripture. The Hadith, or corpus of prophetic sayings, follows suit, as does the tradition in general. The relevant primary literature is vast, and nothing like an adequate survey of important texts has been written. As for the significance of Muslim eschatological teachings, most of the secondary literature seems to agree with Fritz Meier, who writes, “The basic concept of the ultimate origins and the hereafter in Islam... is not characterized by any particular originality, and as a system is no more satisfying than the corresponding Judeo-Christian one.” A good deal of more recent research, however, suggests that the original contributions of Muslim scholarship were just beginning to develop at the point where Meier leaves off, that is, around the time of Ibn Rushd (Averroes), who died in 1198. This article explores the eschatology of Muslims, realms of posthumous becoming, principles of Islamic theology, prophecy, eschatology, the two worlds, the Isthmus, the divine form, the soul, and the origin and return.
