He also wrote a commentary on the Zij as-Sindhind, and measured the coordinates of Mecca. Ibn as-Saffar later influenced the works of Abu as-Salt. Paul Kunitzsch argued that a Latin treatise on the astrolabe long attributed to Mashallah, and used by Chaucer to write A Treatise on the Astrolabe, is in fact written by Ibn as-Saffar. The exoplanet Saffar, also known as Upsilon Andromedae b, is named in his honor. Saffar Island in Antarctica is named after Ibn as-Saffar. (en)
