These are disciples of Khwájah Aḥmad Yasawí. In his youth he was under the supervision of Báb Arslán, who was an eminent spiritual guide among the Turks. On his death he profited by the instruction of Khwájah Yúsuf Hamadání. The Turks call him A´tá Yasawí; A´tá in Turkish signify­ing a father, and their saints are thus designated.* He returned to Turkistán at the command of the Khwájah and ended his days in the spiritual instruction of the people. Many miracles are reported of him. Four spiritual delegates are celebrated as religious guides: Manṣúr A´tá, Sạíd A´tá, Sulaymán A´tá, and Ḥakím A´tá. Yasí is a town in Turkistán, the birthplace and town of this Shaykh.
