In the mid-15th century, he was active as a mu'allim, a pilot for voyages in the Indian Ocean. His birth and death years are unknown. His father and uncle were also famous pilots. He is known to have written 22 books on navigation, compass points, astronomy, geodesy, etc. These books are, so to speak, a refined and compiled maritime knowledge possessed by Arab-Persian navigators who had been active in the Indian Ocean for several thousand years, and their advanced navigational techniques and precise and detailed geographical knowledge are astonishing.
