Thinking & assuming of Life & Death is very easy without taking into consideration of the true facts of this temporary World.
But the reality is different, everyone after spending some time will face the Death & will be no more in this world, that is for sure. History is Proof. We cannot see Hitler now, where he has gone? What will happen to his Deeds which he did in his life? Will he get punishment or will be awarded? Sure there will be some kind of judgment still pending for the past people & future generation too. This is the belief in Islam.
Islam is the only religion on this earth which defines the true meaning of the DEATH and the LIFE after Death (which never Ends).
Death means transfer of soul from this real world to the Creator (Allah). Allah keeps all the souls in the sky since ADAM till the End of this World ("Qayamat" as mentioned in Quran). There will be a rebirth of the mankind and gathering on a Hashar ka Maidan (Judgment Day). Allah will check the complete report of everyone's good & bad DEEDS (not the Money & Status). Believe it or not, every moment of our life is recording, whether we are doing good or bad, it is recorded. NO ONE has the right to change it afterwords. Every day in evening the Angles turning the PAGE of that Day & will open it again on the Judgment Day!.
Yes, it is the Islam. Everyday in morning our PAGE is empty like blank Excel Sheet with Date, Time, Place, Event, and INTENTION etc etc.and which is filled by the Angels. Do you know where are the Angels who write our Deeds everyday? Believe it or Not, they are with us always and sitting on our SHOULDERS. The Right shoulder Angel writes the Good Deeds, and the Left shoulder Angel writes the Bad Deeds.
We human being have brain to use it properly and as per guided by Prophet Muhammad (Peace Be Upon Him) should fill the sheet with Good Deeds. Only one's behavior is recording.
At Judgment Day, Angels will produce these Records to Allah. After analysis of records and based on our Deeds, Allah will give back the FINAL REPORT to us. People who believe in Allah & His Judgment Day and followed the guidance of Prophet Muhammad (PBUH) will receive the Report in RIGHT HAND, then it is considered to be the Entry Ticket to HEAVEN. If god-forbidden, one receives the Report in his/her LEFT HAND, then it is considered to be the Entry Ticket to HELL. This is FINAL JUDGMENT. No one can deny it. Those who get report in Left Hand will seek Allah's permission to send him/her back to this real World again, to do good deeds this time. Allah will say, No my son, you lost the opportunity. No more world & no more good deeds. Allah will tell Angles to take him/her to Hell.
For those people who receive report in Right Hand, will be very happy as they will enter into Heaven. The Life in Heaven & Hell will never ends (as mentioned in Quran).
Actually there are many things I can write about it. But you can always read Quran to know more.
