Sibt al-Maridini taught mathematics and astronomy in the Great Mosque of al-Azhar, Cairo. He was also a timekeeper (muwaqqit) of the mosque.[citation needed] He wrote no fewer than fifty[citation needed] treatises in astronomy (sine quadrants, sundials, astronomical tables and prayer times[citation needed]) (Young (2007)) and wrote at least twenty-three mathematics textbooks.[citation needed]
Al-Sakhawy counted two hundred books that were written by Sibt al-Maridini, on Islamic law, astronomy, and mathematics. Libraries that specialize in ancient manuscripts, all over the world, have transcripts of his works.
Sibt al-Mardini’s declared that “the opinion of the muezzins (those who call people to prayer) is less correct than that of the legal scholars and it is the latter that should be used as the basis for the determination of prayer time”.[citation needed]
