is the general, name of the four months which, among the Mohammedans, as well as among the ancient Arabians, were regarded as sacred. These months were Moharram, Resjele, Dulkadha, and Dulhaggia. No war could be lawfully begun or carried on in these months; and most of the Arabian tribes observed this 'so punctually that even the murderer of a father or brother was not to be punished or any violence offered to him at that time. The institution of the sacred months is recognised in the Koran, and their careful observance enforced, except in the case of war against infidels.
