"Believers, Jews, Christians, and Sabi'un-whoever believes in Allah and the Last Day and does what is right-shall be rewarded by their Lord; they have nothing to fear or to regret." This language is repeated in the second citation. The third appearance is slightly different: "As for true believers, the Jews, the Sabi'un, the Christians, the Magians, and the pagans, Allah will judge them on the Day of Resurrection. He bears witness to all things." 1 Early Islamic commentators often disagreed on the identity of the Sabi'un, and the confusion continued throughout the medieval Islamic period. 2 The term Sabi'un was applied by some early Koranic commentators to the survivors of an ancient Jewish-Christian sect, the Elchasites in southern Iraq. 3 One minority group of ethnic Arab "pagans" with a hellenized elite in Harran, in Arabia, also took the Koranic name Sabian in the third/ninth century to claim the status of a "people of the book" and therefore avoid persecution. It is this group that some later Muslims identified as Sabi'. 4 The scholarly consensus now suggests that the 5 Encyclopedia of Islam, "SABI'A." 6 Josef Stern, Problems and Parables of Law: Maimonides and Nahmanides on Reasons for the Commandments (Ta'amei Ha-Mitzvot) (Albany, 1998). 7 Maimonides, Guide for the Perplexed, tr.
