Tarikh-i guzida however says that the Ghorids were only converted to Islam by Mahmud. Conversion of Pashtun-Afghan people The name Afghanistan was first used in a political sense by Saifi Herawi in the 14th century. It was even used during the height of the Durrani Empire. Only after the Durand line was fixed, did its modern usage for the land between it and the Oxus river become usual. The people who were mostly responsible for establishing the Afghan kingdom are referred to as Pashtun, who were also called "Afghans". The name Pashtun (or Pakthun) is the original and oldest name. The tenth-century Persian geography Hudud al-'Alam is the earliest known mention of the Afghans. In Discourse on the Country of Hindistan and Its Towns, he states that, "Saul, a pleasant village on a mountain. In it live Afghans." Ibn Battuta described Saul as being situated between Gardez and Husaynan along a common trade route, the exact location of Husaynan is unknown. Akhund Darweza states that their original homeland was Qandahar from where they migrated in 11th century upon the request of Mahmud of Ghazni to assist him in his conquests. Afghan tradition considers "Kase Ghar" in Sulayman range as the homeland. Hudud al-'Alam also mentions that the king of Ninhar (Nangarhar) had many wives including "Moslem, Afghan and Hindu". The Pashtun traditions speak of Islamization during Muhammad's time through Khalid ibn Walid. Qais Abdur Rashid, the presumed ancestor of the Afghans, is said to have led a delegation to Mecca from Ghor after being summoned by Khalid b. Walid and converted to Islam while also distinguishing himself in the service of Muhammad. He adopted the name Abdul Rashid, and his three sons – Saraban, Ghurghust, Karlani, and a foundling Karlanri linked to Saban, are considered to be the progenitors of the major Afghan divisions. Ni'matullah's Makhzan-i-Afghani traces their history to an Israelite called Afghana who constructed the al-Aqsa mosque. Per it, under the time of King Suleiman, a figure named Bokhtnasser was responsible for "carrying away the Israelites, whom he settled in the mountainous districts of Ghor, Ghazneen, Kabul, Candahar, Koh Firozeh, and the parts lying within the fifth and sixth climates; where they, especially those descended of Asif and Afghana, fixed their habitations, continually increasing in number, and incessantly making war on the infidels around them." Qais traveled to Medina to receive Mohammed's blessings and fought against the Meccans.
