[550] Túsí is the name of several celebrated men from the town of Tús. There are two towns of that name: the one in Transoxana, in the domain of Bochára; the other in Khorasan; the latter consists of two towns, one is called _Tabaran_, the other _Núkan_.――(_Abulfeda_, _Annales Moslemica_, vol. III. p. 375.) We know several authors named _Abú Jâfar_, to whom the words above quoted may be attributed, none with the surname _Túsí_. The author above meant is perhaps _Abú Jâfar al Tabarî_, celebrated historian, born in the year of the Hejira 224 (A. D. 838), deceased in 310 (A. D. 922). [551] The twelve Imáms are as follow: I. ALÍ, khalif and Imám, was murdered A. D. 661. II. HASAN, eldest son of Alî, khalif and Imám, poisoned A. D. 669. III. HOSAIN, the second son of Alí, killed in battle A. D. 680. IV. ALÍ, surnamed _Zin alâbedin_, eldest son of Hosain, died A. D. 712. V. MUHAMED BEKER, son of Alí, poisoned A. D. 734. VI. JAFR SADIK, son of Muhammed, died A. D. 765. VII. ISMÁIL, son of Jáfr; see hereafter the account of the Ismâilah. Herbelot names, as the seventh Imám, Mussa, the second son of Jáfr, surnamed _al Kiadhem_, “the debonnair,” and also _saber_, “the patient,” and _ámin_, “the faithful guardian.” The latter died A. D. 799. VIII. ALÍ REZA, son of Mussa, poisoned A. D. 816. IX. MUHAMMED, son of Alí Reza, called also _Abú Jafr Muhammed_, died A. D. 835. X. ALÍ ASKERÍ, son of Muhammed, poisoned A. D. 868. XI. HASAN, son of Alí Askerí, died poisoned A. D. 873. XII. MUHAMMED, son of Hasan, surnamed _Mahadi_, “conductor, director;” he is supposed to be still living, and expected to appear with the prophet Elias, at the second coming of Jesus Christ. It may be remarked that, of the twelve holy men, seven died a violent death, and two in an unknown manner. [552] I follow here the French translation of the Arabic text, made by M. Garcin de Tassy.――(See _Journal asiatique_, _mai 1842_, pp. 436-439.) [553] _Ad_ was an ancient and potent tribe of Arabs in the province of Hadramaut. They chiefly worshipped four deities; _Sakia_, supplying them with rain; _Háfedha_, preserving them from all dangers abroad; _Rázeka_, providing them with food; and _Sálema_, restoring the sick to health. Frequent mention of them occurs in the Koran. [554] The tribe of _Tamud_ dwelt first in the country of the Adites, then removed to the territory of Hejr, where their habitations, cut in the rocks, are seen at this day. (See Sale’s Koran, vol. I, pp. 7. 9. 196. 199.) [555] Moavia.
