Prophet David was a just and righteous ruler who brought peace and prosperity to his people, and whom Allah honored as a messenger. He delivered Allah's message to the people through the precious gift of his melodious voice. When he recited the Psalms (Zaboor) it was as if the rest of creation chanted with him; people listened as if in a trance. The messages David delivered are famous and well remembered. They are known in the Bible as the Psalms or Songs of David.
David divided his working day into four parts: one to earn a living and to rest, one to pray to his Lord, one to listen to the complaints of his people, and the last part to deliver his sermons. He also appointed deputies to listen to his subjects' complaints so that in his absence people's problems might not be neglected.
Although a king, he did not live on the income of his kingdom. Being well-experienced in the craft of weapon-making, he made and sold weapons and lived on that income.
