Martyrdom, since it is a theme within Islam, has been given a set form by tradition (both the Islamic tradition as well as the martyrdom tradition of religions that preceded it). This form often demands that the martyr be given knowledge of his or her death just prior to its occurrence, either in a dream/vision by means of an earthly figure who is privy to divine or supernatural knowledge, or occasionally by the drama that leads up to his or her death. Sometimes there are dreams or visions that occur after the martyr's death as well, so that the audience knows he or she has been suitably rewarded. Usually the martyr must die in a dignified manner, to the extent that such a death is possible under the circumstances, with his or her faith untainted, and have the ability or opportunity to speak to the audience before death supervenes.
