Muḥammad al-Akhṣāṣī al-Muwaqqit (Arabic: محمد الاخصاصي الموقت‎) was an Egyptian astronomer whose calendarium and catalogue of stars, al-Durrah al-muḍīyah fī al-ʻamāl al-shamsīyah ("Pearls of brilliance upon the solar operations"), was written at Cairo about 1650.[1] Al-Akhsasi was a shaykh, a learned elder, of the Grand Mosque of the university of Cairo, where his name al-Muwaqqit reflected his position regulating the times and hours at the mosque. His name Akhsasi connects him in origin to a village in the Faiyum.[2]

No copies of his book were known to Western astronomers or historians of science until 1895;[3] thus he did not appear in the standard French and English bibliographies and library catalogues of the 19th century.
