When Hassan left Isfahan, in the year 1078, the khalif Mostanser, a man of some energy, occupied the throne of Egypt, and considerable exertions were made by the missionaries of the society at Cairo to gain proselytes throughout Asia. Among these proselytes was Hassan Sabah, and the following account of his conversion, which has fortunately been preserved in his own words, is interesting, as affording a proof that, like Cromwell, and, as we have supposed, Mohammed, and all who have attained to temporal power by means of religion, he commenced in sincerity, and was deceived himself before he deceived others. "From my childhood," says he, "even from the age of seven years, my sole endeavour was to acquire knowledge and capacity. I had been reared up, like my fathers, in the doctrine of the twelve imams, and I made acquaintance with an Ismaïlite companion (_Refeek_), named Emir Dhareb, with whom I knit fast the bonds of friendship. My opinion was that the tenets of the Ismaïlites resembled those of the Philosophers, and that the ruler of Egypt was a man who was initiated in them. As often, therefore, as Emir said anything in favour of these doctrines I fell into strife with him, and many controversies on points of faith ensued between him and me. I gave not in to anything that Emir said in disparagement of our sect, though it left a strong impression on my mind. Meanwhile Emir parted from me, and I fell into a severe fit of sickness, during which I reproached myself, saying, that the doctrine of the Ismaïlites was assuredly the true one, and that yet out of obstinacy I had not gone over to it, and that should death (which God avert!) overtake me, I should die without having attained to the truth. At length I recovered of that sickness, and I now met with another Ismaïlite, named Aboo Nejm Zaraj, of whom I inquired touching the truth of his doctrine. Aboo Nejm explained it to me in the fullest manner, so that I saw quite through the depths of it. Finally I met a dai, named Moomin, to whom the sheikh Abd-al-Melik (_Servant of the King_, i. e. _of God_) Ben Attash, the director of the missions of Irak, had given permission to exercise this office. I besought that he would accept my homage (in the name of the Fatimite khalif), but this he at the first refused to do, because I had been in higher dignities than he; but when I pressed him thereto beyond all measure, he yielded his consent. When now the sheikh Abd-al-Melik came to Rei, and through intercourse learned to know me, my behaviour was pleasing unto him, and he bestowed on me the office of a dai. He said unto me, 'Thou must go unto Egypt, to be a sharer in the felicity of serving the imam Mostander.' When the sheikh Abd-al-Melik went from Rei to Isfahan I set forth for Egypt[25]."
