Sandschaki or Sandschaki-sherif [the standard of green silk].
The sacred banner of the Mussulmans. It is now enveloped in four coverings of green taffeta, enclosed in a case of green cloth. The standard is twelve feet high, and the golden ornament (a closed hand) which surmounts it holds a copy of the Koran written by the Calif Osman III. In times of peace this banner is guarded in the hall of the noble vestment, as the dress worn by the prophet is styled. In the same hall are preserved the sacred teeth, the holy beard, the sacred stirrup, the sabre, and the bow of Mahomet.
