Every living creature is destined to die. This is the natural law. Or everything that is born will die. To the Muslims this is the law of Allah(swt). Hence human beings are no exception. Death is the cessation of ordinary human existence. Questions concerning the origin of death and the destiny of the dead, as well as rituals regarding the dead, are elements in all religions.
In Islam, death is the common destiny willed by Allah(swt) for all living things. Death is a passing state for human beings between earthly existence and immortal life in the hereafter(Aakhirah). The onset of death is traditionally conceived in terms of a personal encounter with an angel of death dispatched by Allah(swt). Prevailing Islamic doctrine conceives death as a disengagement of the soul from the body, the outward sign of which is the cessation of breathing. This event marks the end of the predetermined period of mundane life that is to be accounted for at the last judgment, the Day of Judgment(Qiyamah), when the body and soul are again reunited and resurrected for consignment to the splendid gardens of paradise or torturous fires of hell. Between death and resurrection, individuals are subjected to a preliminary trial in the grave by the angels Munkar and Nakir and given a preview of their destiny in the Hereafter (Aakhirah).
The principal points of the Muslim Creed are: Belief in Allah (the God), God's Angels, God's Messengers, God's Books, Belief in life after death (Aakhirah); the Day of Resurrection (Qiyamah) and Qadr.
The fifth point in Muslim creed is to believe in life after death; to believe in the Day of Resurrection. This is the most important article of faith in Islam. It is in fact, the basis upon which Islam builds its whole philosophy of Life. A person cannot be a Muslim until after he/she accepts this principle. The advent of resurrection or Qiyamah is more frequently mentioned in the Noble Quran than any other happening. On the day of Qiyamah, all human beings will be resurrected and will have to pass through God's judgment on their actions during this ephemeral life on earth. All this is vividly described in the Noble Quran. The word, Qiyamah, occurs 68 times in the Quran, and the word Hereafter occurs 118 times in Yusuf Ali's translation of the Quran. The Quran argues that resurrection is rationally possible.
