Islamic "Symbolism"

I've known these many years ago but I thought I should share it nevertheless.

When does green became the "color of Islam" and since when did the Crescent, or sometimes Crescent and star(s) became Islamic symbols? These symbols have never been used during the time of the Prophet. Though I don't object to the usage I very very strongly urge for the Ummah or Muslim populace to understand the history and nature of these symbols. Understand that these are merely symbols adopted MUCH later and has nothing to do with Islam.

One reason it is important because certain so-called learned "intellectuals" had proposed the idea of Allah being the "moon-god"... *LOL* *LOL* & a BIG *ROFL*... These dimwits either no NOTHING of the real history or simply want to sow doubts within the Islamic community, to weaken our faith. But that deserves a very lengthy discussion worth hundreds of pages. Of course with tonnes of proof that Allah, El, Elohim, Alaha all refer to the same Almighty Supreme Being.

Reminds me of the time when a group of Jehovah's Witnesses came to me and one of them told me that "Muhammad was raised by Jews".. ANOTHER BIG *ROFL* then... As I was trying to compose myself after laughing so hard (inside), he told me to look it up in my University's library... I almost died from laughing too hard (inside of course)... Well, the prophet Muhammad was a descendant of Adnan, and some consider Adnanites to be a Jewish tribe probably since they are Ismaelites which are very closely related to the Israelites. Well, they are arabicised arabs. Not the pure arabs which are descended from Qahtan (Joktan). But I believe the Prophet Ishmael (Isma'il) did marry an arab so that makes his descendants to be of mixed blood. Not to mention Egyptian, from Hagar (Malays call her Siti Hajar) an Egyptian princess. A princess which the Pharaon gave to Abraham as a midwife.
