Sarakhs
Sarakhs, on the border of present-day Iran and Turkmenistan in the historic region of Khurasan, was a town on the road between Nishapur and Merv. The Hanafi jurist al-Sarakhsi (d. c. 1096), author of the major legal compendium al-Mabsut, which he is said to have dictated from prison, took his nisba from the town.
