What does the crescent moon and star mean in the Muslim flag?

Answer 1

The star and crescent are not symbols per Islam religion; as for example the cross in Christianity. They were just some traditional or historical symbols that by time attached to the religion. They were the symbols of the Ottoman Turkish empire. During the Crusades, the symbol came to be associated with Islam. In reality, Muslims view the stars and moon as creations of God.

AnswerThe Crescent moon, often with a five or six pointed star, became a prominent symbol for Islam early in the 19th century. The Ottoman sultan Selim III (r. 1789-1807) used this symbol for the imperial flag of his military, in imitation of official flags in Europe.

Later in the twentieth century under Ottoman influence, a number of countries with Muslim majorities adopted variations of the crescent and star for their own flags, while the Red Crescent Organization became the Muslim equivalent to the Red Cross.

Though the crescent and star have only recently become a popular world-wide symbol for Islam, crescents and stars were marked features of official coins, mosques, banners, textiles, and ceramics produced in Islamic lands since the seventh century.

Further, given the official lunar calendar of Islam, the crescent of the new moon has had an important ritual and legal role in signaling the beginning and end of the fast of Ramadan, as well as the date of the Hajj, the great annual pilgrimage to Mecca.

Finally, according to popular tradition, whenever the Prophet Muhammad first caught sight of a new moon he would say: "O crescent moon of good and guidance, my faith is in Him who created you!"
The star and crescent is a symbol of the Turkish empire, and has no particular significance to Muslims in general.

Answer 2

The crescent moon and the flag, contrary to popular belief, were risen in the 1400's by the Ottoman Turkish Empire, long after the founding of Islam, and long after many successful Islamic Empires (the Caliphates) had come and gone.

It has no Islamic connotation, but has become a pusedo-symbol for Muslims. Muslims do however, follow the lunar calendar, as the Jews do, and thus man "rings" above mousques may be attributed to the calendar trends.

Muslims have very few religious symbols out-side of Holy Text from the Quran, and the words of the Prophet, as idolity is forbidden in Islam.
