Pir Muhammad
Upon his father's appointment as viceroy of Fars in 1393, Iskandar and his family were transferred from his birthplace of Uzgand to join Umar Shaikh at Shiraz. Soon after, both his father and elder brother Pir Muhammad were summoned to re-join the Timurid army, leaving the young Iskandar as the nominal governor in Umar Shaikh's stead. Upon the latter's death the following year, this role was given to Pir Muhammad while Iskandar and other family members accompanied Umar Sheikh's bier for burial in Kesh.
