There was a man named Ali, who resided in the city of Rei, in Persia. He was a strenuous Sheäh, and maintained that his family had originally come from Koofa, in Arabia; but the people of Khorasan asserted that his family had always dwelt in one of the villages near Toos, in that province, and that consequently his pretensions to an Arabian extraction were false. Ali, it would appear, was anxious to conceal his opinions, and employed the strongest asseverations to convince the governor of the province, a rigid Soonite, of his orthodoxy, and finally retired into a monastery to pass the remainder of his days in meditation. As a further means of clearing himself from the charge of heresy he sent his only son Hassan Sabah[22] to Nishaboor to be instructed by the celebrated imam Mowafek, who resided at that place. What lessons he may have given the young Hassan previously to parting with him, and what communication he may have afterwards kept up with him, are points on which history is silent. [Footnote 22: Or Hassan-ben-Sabah (_son of Sabah_), so named from Sabah Homairi, one of his pretended Arabian ancestors.] The fame of the imam Mowafek was great over all Persia, and it was currently believed that those who had the good fortune to study the Koran and the Soonna[23] under him were secure of their fortune in after-life. His school was consequently thronged by youths ambitious of knowledge and future distinction; and here Hassan met, and formed a strict intimacy with, Omar Khiam, afterwards so distinguished as a poet and an astronomer, and with Nizam-al-Moolk (_Regulation of the Realm_), who became vizir to the monarchs of the house of Seljook. This last, in a history which he wrote of himself and his times, relates the following instance of the early development of the ambition of Hassan. As these three, who were the most distinguished pupils of the imam, were one day together, "It is the general opinion," said Hassan, "that the pupils of the imam are certain of being fortunate. This opinion may be verified in one of us. So come, let us pledge ourselves to one another that he who shall be successful will make the other two sharers in his good fortune." His two companions readily assented, and the promise was mutually given and received. [Footnote 23: The Soonna is the body of traditions, answering to the Mishua of the Jews, held by the orthodox Mussulmans.]
