"Many Muslim scholars reject using the crescent moon as a symbol of Islam. The faith of Islam historically had no symbol, and many refuse to accept it."

The symbolism of the star and crescent in the flag of the Kingdom of Libya (1951-1969) was explained in an English language booklet, The Libyan Flag & The National Anthem, issued by the Ministry of Information and Guidance of the Kingdom of Libya (year unknown, cited after Jos Poels at FOTW, 1997) as follows: "The crescent is symbolic of the beginning of the lunar month according to the Muslim calendar. It brings back to our minds the story of Hijra (migration) of our Prophet Mohammed from his home in order to spread Islam and teach the principles of right and virtue. The Star represents our smiling hope, the beauty of aim and object and the light of our belief in God, in our country, its dignity and honour which illuminate our way and puts an end to darkness."
