The red in the background is the representation of the Turkish military (soldier) blood leaked all over the river bed! In the evening a moon and star appeared side by side (which is quite rare) and reflected on the pool of blood, hence the importance of the flag to the Republic of Turkey! The term 'Ay Yildiz' is just an expression of the symbolic representation of the moon and star!
The Current Turkish flag derived from the previous Ottoman empire flag with many changes made!
In addition the moon and star is not a significant symbol in Islam, to be honest there is NO significance of the moon and star in Islam at all!
Historical facts.
Red has been prominent in Turkish flags for 700 years. The star and crescent * are Muslim symbols, but also have a long pre-Islamic past in Asia Minor. The basic form of the national flag was apparently established in 1793 under Sultan Selim III, when the green flags used by the navy were changed to red and a white crescent and multipointed star were added. The five-pointed star dates from approximately 1844. Except for the issuance of design specifications, no change was made when the Ottoman Empire became the Republic of Turkey and the Caliphate (religious authority) was terminated. Many traditions explain the star and crescent symbol. It is known that Diana was the patron goddess of Byzantium and that her symbol was a moon. In 330, the Emperor Constantine rededicated the city - which he called Constantinople - to the Virgin Mary, whose star symbol was superimposed over the crescent. In 1453 Constantinople was captured by the Ottoman Turks and renamed Istanbul, but its new rulers may have adopted the existing emblem for their own use.
Legends.
A reflection of the moon occluding a star, appearing in pools of blood after the battle of Kosovo in 1448 **, led to the adoption of the Turkish flag by Sultan Murad II according to one legend. Others refer to a dream of the first Ottoman Emperor in which a crescent and star appeared from his chest and expanded, presaging the dynasty's seizure of Constantinople. At least three other legends explain the flag.
