The standard form of body armor was chainmail. There are also references to the practice of wearing two coats of mail ("dir’ayn"), the one under the main one being shorter or even made of fabric or leather. Hauberks and large wooden or wickerwork shields were also used as protection in combat. The soldiers were usually equipped with swords hung in a baldric. They also possessed spears and daggers. Umar was the first Muslim ruler to organize the army as a state department, in 637. A beginning was made with the Quraish and the Ansar and the system was gradually extended to the whole of Arabia and to Muslims of conquered lands.
