Abu Ja'far ibn Habash
Abu Ja'far ibn Habash was a Persian astronomer. He was most likely a son of Habash al-Hasib. Since his father died after 864 AD at the age of 100, it can be concluded that he was active in 3rd century AH. According to Ibn Nadim and Al-qifti, he wrote a book on astrolabe, named al-ostorlab al-mosatah.
