No other religions are mentioned as such in the Qur'an apart from three references to the mysterious group called Sabaeans (Sabi'iin), in one of which the Magians or Zoroastrians (Majiis) are also mentioned (2.62; 5.69; 22.17). The existence of other religions is allowed for, however, in such verses as 40.78, which speaks of messengers sent by God before Mul:lammad, only some of whose stories have been told him, and 45. 28, where in the course of the Last Judgment unnamed communities are 'called to their Book'. Any such religions, however, were presumably regarded as the result of revelations to a single prophet or messenger, so that there was no place in this conception of religion for any idea of development.
