The Moon God
Orientalists who prefer to indulge in unscholarly distorted fabrications have gone through desperate lengths in order to justify their assertion that Muslims worship a moon god. Critics, with invalid evidence state that the crescent on the dome of mosques and the Muslims use of a crescent logo are an act of worship.
Origin and First use of the Crescent :
The early Muslim community did not have a symbol. During the time of the Prophet Muhammadﷺ , Islamic armies and caravans flew simple solid-colored flags (generally black, green, or white) for identification purposes. It wasn't until the Ottoman Empire that the crescent moon and star became affiliated with the Muslim world. When the Turks conquered Constantinople (Istanbul) in 1453, they adopted the city's existing flag and symbol. There is speculation that the five points on the star represent the five pillars of Islam, but this is pure conjecture. The five points were not standard on the Ottoman flags, and are still not standard on flags used in the Muslim world today.
The crescent moon and star symbol actually pre-dates Islam by several thousand years. Information on the origins of the symbol are difficult to confirm, but most sources agree that these ancient celestial symbols were in use by the peoples of Central Asia and Siberia in their worship of sun, moon, and sky gods.
Based on this history, many Muslims reject using the crescent moon as a symbol of Islam. The faith of Islam has historically had no symbol, and many refuse to accept what is essentially an ancient pagan icon. It is certainly not in uniform use among Muslims. Others prefer to use the Ka'aba, Arabic calligraphy writing, or a simple mosque icon as symbols of the faith.
“And of His signs are the night and day and the sun and moon. Do not prostrate to the sun or to the moon,but prostate to Allah , who created them, if it should be Him that you worship.” (Surah Fussilat, 41:37)
“Say, He is Allah[who is] One, Allah, the Eternal Refuge, he neither begets nor is born, nor is there unto him any equivalent.” (Surah Al-Ikhlas 112:1-4)
Last word :
In the religion of Islam, the fundamental belief of Muslims is to only worship Allah.
