Allah's prophets are His messengers to humanity. Their essence is human, and they are the purest of human beings. Allah sent each prophet as a warner to his community, until the advent of the final prophet, Muhammad (pbuh), who came as a mercy to all of Allah's creatures. Allah the Almighty declared : We have sent you (O Muhammad) not but as a mercy for the Alamin (mankind, jinn and all that exists). (Ch 21:107)
