Ahmad Yasawi (Kazakh: Қожа Ахмет Ясауи, romanized: Qoja Ahmet Iasaui, قوجا احمەت ياساۋٸ; Persian: خواجه احمد یسوی, romanized: Khwāje Ahmad-e Yasavī; 1093–1166) was a Turkic[1][2] poet and Sufi, an early mystic who exerted a powerful influence on the development of Sufi orders throughout the Turkic-speaking world.

[4][5] He was a pioneer of popular mysticism, founded the first Turkic Sufi order, the Yasawiyya or Yeseviye, which very quickly spread over Turkic-speaking areas.

Consequently, it was recognized that, with respect to his lineage as well, this quiet and unassuming young boy, who always listened to his elder sister, held a spiritually important position.

He then turned this position to Abdul Khaliq Ghijduwani under Hamadani's advice and moved to Turkistan City in order to spread Islam in Turkestan.

[7] Ahmad Yasawi made considerable efforts to spread Islam throughout Central Asia and had numerous students in the region.

[10] Yasawi turned the city of Iasy into the major centre of learning for the Kazakh Steppe, then retired to a life of contemplation at the age of 63.

Muhammad then repeated his question, and finally Arystan-Bab replied: "If you beg Allah to give me 400 years of life, then I will pass this date.

"[16] According to legend, Ahmad Yasawi predicted Timur in his dream (who lived two centuries after him) glad tidings of the forthcoming conquest of Bukhara.
