.
Syed Zain ud din Daud was born at Shiraz in Hijri. 701 and went to Delhi by way of Mecca. He studied under Maulana Kamaluddin of Samana, and came with him to Daulatabad. The author of the "Mayrat-al Walayeh" mentions that Zainuddin on his arrival at Daulatabad, disapproved of the singing and dancing in the convent of Burhan uddin; but when he visited the " tekkieh", he was perfectly satisfied, and he and his companions were initiated in the Chishtia order. Syed Zain uddin held the office of "kazi" at Daulatabad, and in H. 737 was invested with the mantle of the kaliphat, but did not actually succeed till after Burhan ud din's death in H. 741. Syed Husain has recorded all the sayings of Zain uddin in his "Hidayat ul Kalul", and mentions that in H. 747, sultan Muhammad bin Tughluq directed him to leave for Delhi with the other inhabitants. After the death of the sultan, his successor Firoz Shah permitted the saint to return to Daulatabad.
Zain uddin was greatly respected by the Bahmani king sultan Mahmud, who was first reproved by the saint for misgovernment. Malik raja the founder of the Faruki dynasty of Kandesh became one of Zain uddin's disciples, and when the next sovereign Nasir ud din Nasir Khan Faruki captured Asirgarh in A.D. 1399, Zain uddin went expressly from Daulatabad to Asirgarh, to tender his congratulations. It was to commemorate this visit that the town of Zainabad, on the left bank of the Tapti, was founded after him; and Burhanpur on the opposite bank was founded about the same time in honor of Burhan ud din.
