Estakhri created the earliest known account of windmills. His Arabic language works included masalik al-mamalik (مسالك الممالك, "Traditions of Countries") and Suwar al-Aqaaleem ( صور الاقاليم, "Shapes of the Climes").
He was a traveller whose geographical work has been translated into German by Mordtmann. When Istakhari was in the Indus Valley he met another celebrated traveller, Ibn Haukul.
