<P> Prominent cases of modern geocentrism in Islam are very isolated . Very few individuals promoted a geocentric view of the universe . One of them was Ahmed Raza Khan Barelvi, a Sunni scholar of Indian subcontinent . He rejected the heliocentric model and wrote a book that explains the movement of sun, moon and other planets around the Earth . The Grand Mufti of Saudi Arabia from 1993 to 1999, Ibn Baz also promoted the geocentric view between 1966 and 1985 . </P> <P> The geocentric (Ptolemaic) model of the solar system is still of interest to planetarium makers, as, for technical reasons, a Ptolemaic - type motion for the planet light apparatus has some advantages over a Copernican - type motion . The celestial sphere, still used for teaching purposes and sometimes for navigation, is also based on a geocentric system which in effect ignores parallax . However this effect is negligible at the scale of accuracy that applies to a planetarium . </P>
