Everyone in this world is well aware of the fact that this life is mortal. All of us are sent in to this world for some specific time after that we have to dwell in eternal life which starts after the end of this life.
Humans pass through different phases after the death i.e. separation of soul from body, life, in grave and the most important event that will happen on the Day of Judgment is when we will be held accountable for our deeds and when we will be questioned by our Lord Allah (S.W.T.) as He says in Quran:
“Then surely, We shall question those (people) to whom it (the book) was sent and verily, We shall question the Messengers.” ( Al-Araf, 6 and 7)
Two Methods of Accountability
On the Day of Judgment, every human being who is sent into this world in any era will be stood together at a place where they will be held accountable in front of God as He says in Quran:
“The Day is approaching when every soul shall find itself confronted with whatever good it has done and whatever evil it has wrought. It will then wish there is a wide space between it and the Day! Allah warns you to beware of Him; He is most tender towards His servants.” (Surat Al-Imran, 30)
There will be two methods of accountability,
Those who have successfully spent their lives according to the teachings of Allah and His Prophet (PBUH) will be directly sent to the paradise to live an eternal life with all the blessing they have been promised for and will be considered as the most successful people.
They will say: “Praise be to Allah Who has fulfilled His promise to us and made us the inheritors of this land, letting us settle in Paradise wherever we want. How excellent is the wage of those who work.” (Surat az-Zumar, 74)
Those who used to commit evil things in the worldly life will be questioned about their bad acts and surely they will have no answer for it except shame on their own deeds and begging pardon for their wrongdoings but the time of forgiveness will be over. Those people will be sent to hell fire where they will be tortured for their sins until they complete their punishments.
