 According to Mihaj's "Tabaqat-i Nasiri", he was a handsome and intelligent boy, because of which his brothers grew jealous of him; these brothers sold him to a slave dealer at a horse show.Minhaj's narrative appears to be inspired by the Quranic story of Hazrat Yusuf (Joseph), who was sold into slavery by his jealous brothers.According to Minhaj, as a young boy, Iltutmish was brought to Bukhara, where he was re-sold to the local "Sadr-i Jahan" (officer in charge of religious matters and endowments).
