Angels are a creation of God. They are purely spiritual and splendid beings that require no food or drink or sleep. They have no physical desires or material needs. Like other creations of God, Angels spend their time worshiping God. In contrast to human beings, Angels do not have free Will – they can only obey God and do not have the ability to disobey Him. Each Angel is charged with a certain duty. Angels cannot be seen by the naked eyes.
