Hello,
Masons also use the bible along with the Quran, and they also use the Hindus books. I didn't read all of your post but I will soon. ANyway, those symbols are not Islamic. Islam as a matter of fact has no symbol. All those symblos that you see nowadays has been adopted hundreds of years after the death of prophet Muhammad (pbuh). The flag of Muslims at the time of the Prophet and his caliphs was blank white or green.
