Here it was that his younger son, Jelālu-’d-Dīn Muhammed, the future author of the Mesnevī, attained to man’s estate, being then eighteen years old; when, in A.H. 623 (A.D. 1226), he married a young lady named Gevher Khātūn, daughter of the Lala Sherefu-’d-Dīn, of Samarqand. She gave birth in due course to Jelāl’s eldest son, ‘Alā’u-’d-Dīn. The king had now returned to his capital, Qonya (the ancient Iconium). Hearing of Bahā’u-’d-Dīn’s great learning and sanctity, the king sent and invited him to the capital, where he installed him in a college, and soon professed himself a disciple. Many miracles are related as having been worked at Qonya by Bahā’u-’d-Dīn, who at length died there on Friday, the 18th of Rebī’u-’l-ākhir, A.H. 628 (February A.D. 1231). The Sultan erected a marble mausoleum over his tomb, on which this date is recorded. Many miracles continued to occur at this sanctuary. The Sultan died also a few years later, in A.H. 634 (A.D. 1236). (After the death of Bahā’u-’d-Dīn Veled, and the acquisition of still greater fame by his son Jelālu-’d-Dīn, who received the honorific title of Khudāvendgār--_Lord_--the father was distinguished from the son, among the disciples, by the customary title of Mevlānā Buzurg--_the Greater or Elder Master_. The traditions collected by Eflākī, relating to this period, vary considerably from one another on minor points of date and order of succession, though the main facts come out sufficiently clear.) 3. Jelāl’s son, Sultān Veled, related to Eflākī that his father Jelāl used frequently to say, “I and all my disciples will be under the protection of the _Great Master_, my father, on the day of resurrection; and under His guidance we shall enter the divine presence; God will pardon all of us for His sake.” 4. It is related that when the _Great Master_ departed this life, his son, Jelālu-’d-Dīn, was fourteen years old. (This is apparently a copyist’s error for “twenty-four.” Jalāl is said to have been born in A.H. 604--A.D. 1207.) He married when seventeen (or eighteen); and often did he say in the presence of the congregation of his friends, “The _Great Master_ will remain with me a few years. I shall be in need of Shemsu-’d-Dīn of Tebrīz (the capital of Azerbāyjān); for every prophet has had an Abū-Bekr, as Jesus had His apostles.” 5. Shortly after the death of the Great Master Bahā’u-’d-Dīn Veled, news was received by the Sultan ‘Alā’u-’d-Dīn of Qonya of the arrival of Sultan Jelālu-’d-Dīn Kh’ārezm-Shāh on the borders of Asia Minor. The Sultan went and prayed at the tomb of the deceased saint, and then prepared to meet the Kh’ārezmians, who were in the neighbourhood of Erzenu-’r-Rūm (Erzen of the Romans, the ancient Arzes, now Erzerum). Scouts brought in the intelligence that the Kh’ārezmians were very numerous; and great anxiety prevailed among the Sultan’s troops. He resolved to see for himself.
