Muslims Contribution To Science Astronomy Muslims <http://tafreehmazaonline.com/Islam/index.html> have always had a special interest in astronomy. The moon and the sun are of vital importance in the daily life of every Muslim. By the moon, Muslims determine the beginning and the end of the months in their lunar calendar. By the sun the Muslims calculate <http://tafreehmazaonline.com/Islam/islam4.html> the times for prayer and fasting (sawm) <http://tafreehmazaonline.com/Islam/islam7.html> . It is also by means of astronomy that Muslims can determine the precise direction of the Qiblah, to face the Ka'bah in Makkah, during prayer <http://tafreehmazaonline.com/Islam/islam7.html> . The most precise solar calendar, superior to the Julian, is the Jilali, devised under the supervision of Umar Khayyam.
The Qur'an contains many references to astronomy. "The heavens and the earth were ordered rightly, and were made subservient to man, including the sun, the moon, the stars, and day and night. Every heavenly body moves in an orbit assigned to it by God <http://tafreehmazaonline.com/Islam/index.html> and never digresses, making the universe an orderly cosmos whose life and existence, diminution and expansion, are totally determined by the Creator."
