Another legend says that Qais Abdur Rashid, said to be the legendary ancestor of the Pashtun nation, is buried atop Takht-e-Sulaiman, and so it is also locally known as Da Kasī Ghar (د کسي غر, Mount of Qais). According to this legend, his descendants migrated west, north, and south from here. Some people visit the place and make animal sacrifices, usually a sheep or a goat, at the tomb of Qais to help feed the poor. Trips to the mountain is undertaken mostly in summer, since from late November until March the snowfall makes it difficult to climb.Al-Biruni, who himself lived a large part of his life in Ghazni located just northwest of the Sulaimans, writes of the mountains in his memoirs as being the western frontier mountains of Asia and the homeland of an Ajami (non-Arab) tribe known as the Pashtuns.
