Muhammad used flags of different colours in different "Ghazwat" (or campaigns commanded by Muhammad himself) and "Saraya" (or campaigns commanded by Sahabah, the companions of Muhammad). The major flag of Muhammad, the Black Standard, was known as "al-ʿUqāb" "the Eagle"; it was pure black, without symbols or markings. Its name and the colour was derived from the flag of the Quraysh, one of the tribes of Arabia, whose flag was black with an eagle and was also known as "the Eagle"
