Sheikh Edebali

İmâdüddin Mustafa bin İbrâhim bin İnac al-Kırşehrî [1](died in 1326), often known as Sheikh Edebali (Turkish: Şeyh Edebali), was a Muslim Sheikh of the Wafaiyya order (tariqa) and leader of the Ahi brotherhood,[4] who helped shape and develop the policies of the growing Ottoman State.

[2] Edebali was a Sayyid and married his daughter Rabia Bala Hatun to Osman Gazi, the founder of the Ottoman Empire.

[6] Edebali often conversed with his close friend Ertuğrul Gazi, the father of Osman I about Islam and the state of affairs of Muslims in Anatolia.

Edebali became Osman's mentor and eventually gifted him a Gazi sword.

[citation needed] Edebali's advice to his son-in-law, Osman I, shaped and developed Ottoman administration and rule for six centuries.
