This is a story of a seeker of Truth, the story of Salman the Persian, gleaned, to begin with, from his own words. Salman was to play an important role in the struggles of the growing Muslim state. At the battle of Khandaq, he proved to be an innovator in military strategy. He suggested digging a ditch or khandaq around Madinah to keep the Quraysh army at bay. When Abu Sufyan, the leader of the Makkans, saw the ditch, he said, "This stratagem has not been employed by the Arabs before."
