lying within the external or verbal form of the law; and in proportion as a sect exalted Ali, so it diverged from literal acceptance of the Qur’an. The most extreme Shi‘ites, who tended to deify their Imam, were known on that account as Batinites or Innerites. On this more hereafter. [Sidenote: THE SYSTEM OF SEVENS] But to return to the Seveners: in the fourth grade a further refinement was added. Everything went in sevens, the Prophets as well as the Imams. The Prophets had been Adam, Noah, Abraham, Moses, Jesus, Muhammad and Isma‘il, or rather his son Muhammad, for Isma‘il himself had died in his father’s lifetime. Each of these Prophets had had a helper. The helper of Adam had been Seth; of Noah, Shem; and the helper of Muhammad, the son of Isma‘il, was Abd Allah ibn Maymun himself. Between each pair of Prophets there came six Imams—it must be remembered that the world was never left without an Imam—but these Imams had had no revelation to make; were only guides to already revealed truth. Thus, we have a series of seven times seven Imams, the first, and thereafter each seventh, having the superior dignity of Prophet. The last of the forty-nine Imams, this Muhammad ibn Isma‘il, is the greatest and last of the Prophets, and Abd Allah ibn Maymun has to prepare the way for him and to aid him generally. It is at this point that the adherent of this system ceases to be a Muslim. The idea of a series of Prophets is genuinely Islamic, but Muhammad, in Muslim theology, is the last of the Prophets and the greatest, and after him there will come no more.
