Events of the Day of Judgment

Allah states in the Qur'an about the events of the Day of Judgment:

 Then when the Horn is blown with one blast, and the earth and the mountains are lifted and leveled with one blow [i.e. stroke] - Then on that Day, the Occurrence [i.e. Resurrection] will occur, And the heaven will split [open], for that Day it is infirm (i.e. weak, enfeebled and unstable). And the angels are at its edges. And there will bear the Throne of your Lord above them, that Day, eight [of them]. That Day, you will be exhibited [for judgment]; not hidden among you is anything concealed (i.e. any person or any secret you might attempt to conceal). So as for he who is given his record in his right hand, he will say, “Here, read my record! Indeed, I was certain that I would be meeting my account.” So he will be in a pleasant life - In an elevated Garden, Its [fruit] to be picked hanging near. [They will be told], “Eat and drink in satisfaction for what you put forth (i.e. literally, advanced in anticipation of reward in the Hereafter) in the days past.” But as for he who is given his record in his left hand, he will say, “Oh, I wish I had not been given my record, and had not known what is my account. I wish it [i.e. my death] had been the decisive one (i.e. ending life rather than being the gateway to eternal life). My wealth has not availed me. Gone from me is my authority.” [Allah will say], “Seize him and shackle him. Then into Hellfire drive him. Then into a chain whose length is seventy cubits insert him.” Indeed, he did not used to believe in Allah, the Most Great.  (Quran, 69:13-33)

The Prophet Muhammad  taught that three things continue to benefit a [believing] person even after death - charity which he had given (which continues to benefit others), beneficial knowledge which he had left behind (i.e. authored or taught), and supplication on his behalf by a righteous child (Narrated by Saheeh Muslim).

Thus, there are very convincing reasons to believe in life after death:

1)  All the Prophets of Allah have called their people to believe in it.

2)  Whenever a human society is built on the basis of this belief, it has been the most ideal and peaceful society, free of social and moral evils.

3)  History bears witness that whenever this belief is rejected collectively by a group of people in spite of the repeated warning of the Prophet, the group as a whole has been punished by Allah even in this world.

4)  Moral, aesthetic and rational faculties of man endorse the possibility of the life after death.

5)  Allah’s attributes of Justice and Mercy have no meaning if there is no life after death.
