THE DAY OF JUDGMENT
This earth, planets and stars were all created by Allah at a point in time. They did not always exist and they will perish by Allah's will. On a day which only Allah knows (not even the angels or prophets know it), Allah will make everything on earth and in the skies die (including angels, Satan, and all devils) and then He will resurrect them all and judge humans and jinns on what they did during their lives. Because humans and jinn made the choice to be believers or non-believers, pious or sinners, they will be rewarded or punished, by Allah's will, for what they believed, said, and did.
PARADISE (HEAVEN)
Those of mankind and jinn who believe correctly in Allah, and believe in the Messenger sent to them and profess their belief (i.e., becoming followers of the true Religion) and die with that status will dwell forever in Paradise, which Allah has created for them. The life in Paradise is better than what any human living on earth can imagine. Those in Paradise will experience it in body and soul, but the body will be a new body with no defects. Paradise is not allegorical. It is very real and actual. There will be wonderful riches, foods, joy, and peace. People will be married and have interaction with one another. Those in Paradise will be in ranks according to their piety. Those who are rewarded with Paradise will never be sent out of it.
HELL
Hell, another creation of Allah, is the everlasting dwelling place for those of humans and jinn who rejected the revelations of the prophets. Hence, they disbelieved in Allah and His messengers. Hell is also a particular place and is not experienced here on earth. Its torture will not cease. The suffering will also be in body and soul. Some humans who were followers of the true Religion will suffer in Hell for some time, because they had sinned and did not repent of their sins during their lifetime. Being believers of the true Religion, they will get out of Hell after a time which Allah wills. Then they will enter Paradise and dwell there forever and receive no further punishment. Some believers of the true Religion who die as sinners will be forgiven by Allah on the Day of Judgment and will not go to Hell before entering Paradise.
LIFE AND DEATH
This life of a human or jinn always ends with death and there is no exception. Humans do not choose their race, sex, parents, or birthplace and will not be held accountable for those aspects of their life on the Day of Judgment. No human is doomed to Hell because he was born as a certain sex or race. Allah the Merciful, has promised any human or jinn who dies as a follower of the true Religion will receive Paradise forever. Those people who truly never heard about the correct belief in Allah and any of the messengers during their entire lifetime and died in that state will not go to Hellfire. But those sane and pubescent people who have heard of the correct belief in Allah and His messenger and die not embracing this true Religion will dwell in Hell forever.
The correct belief in Allah has never changed and every prophet and messenger has said the same concerning belief in Allah: No one is God but Allah and mankind is to believe in Him and worship Him only. The prophet for the people on earth at present is Muhammad, may Allah's blessings and peace be upon him, and the laws for the present population are the laws that prophet Muhammad was given by Allah for mankind. There will be no new laws given, for there will be no new messenger.
Usually, the person is given one life in this world, so a person is wise to live this life correctly. No matter how appealing it is to some people, they will not "reincarnate" after they die. This and other false beliefs about mankind and Allah are whispered into human's minds by Satan and the devils, and some men are fooled into believing them
