Bahā Veled’s eldest child, his daughter, was married off, and remained at Balkh, when Bahā Veled, his mother, and two sons left it, a year or so before it was taken and devastated by Jengīz Khān in A.H. 608 (A.D. 1211). His elder son is not again mentioned by Eflākī after their departure from Balkh. Neither is the mother of his children once mentioned. But his own mother, the princess, was alive, and was still with him in about A.D. 1230; after which, she too is not again mentioned. Bahā Veled’s youngest child, his most celebrated son Muhammed, surnamed Jelālu-’d-Dīn, Mevlānā, Khudāvendgār, and Rūmī, the principal personage of these memoirs, the founder of the order of the Mevlevī dervishes, and author of the Mesnevī, had four children, three boys and a girl, by two wives. His eldest son was killed in the broil that caused the murder of his father’s friend Shemsu-’d-Dīn of Tebrīz. His youngest son is not taken further notice of; but his daughter was married off to a local prince, and left Qonya. His second son, and eventually his successor as Principal or Abbot of his order, was named Muhammed, and surnamed Bahā’u-’d-Dīn. He is commonly known as Sultan Veled. Sultan Veled had six children, a boy and two girls by his wife Fātima, daughter of Sheykh Ferīdūn the Goldbeater, and three boys, of whom two were twins, by two slave women. The daughters married well, and all his sons, or three of them, succeeded him as Abbot, one after the other. The eldest was Mīr ‘Ārif (Chelebī Emīr ‘Ārif), the second was named ‘Ābid, the third Zāhid, and the fourth Wāhid. Chelebī Emīr ‘Ārif, the eldest, and Eflākī’s patron, had two sons and a daughter. His eldest son, Emīr ‘Ālim, surnamed Shāh-zāda, succeeded eventually to the primacy after his uncles. With him, Eflākī’s memoir is brought to a close. Such was the natural line of this dynasty of eminent men. But Eflākī has also given the links of a spiritual series, through whom the mysteries of the dervish doctrines were handed down to and in the line of Jelālu-’d-Dīn. In the anecdote No. 79, of chapter iii., the account is given of the manner in which the prophet Muhammed confided those mysteries to his cousin, son-in-law, and afterwards his fourth successor, as Caliph, ‘Ālī son of Abū-Tālib, the “Victorious Lion of God.” ‘Ālī communicated the mysteries to the Imām Hasan of Basra, who died in A.H. 110 (A.D. 728); Hasan taught them to Habīb the Persian,[36] who confided them to Dāwūd of the tribe of Tayyi’,--Et-Tā’ī (mentioned by D’Herbelot, without a date, as Davud Al Thai; he died A.H. 165, A.D. 781).
