According to the Encyclopaedia of Islam, the theory of Pashtun descent from the ancient Israelites is traced to Tārīkh-e Khān Jahānī wa Makhzan-e Afghānī (تاریخ خان جهانی ومخزن افغانی), a history compiled by Nimat Allah al-Harawi during the reign of the Mughal emperor Jahangir in the 17th century. The Makhzan-e Afghānī's Israelite theory, however, has been dismissed by modern authorities due to numerous historical and linguistic inconsistencies.
