Quick answer: Belief in the Day of Judgment (Qiyamah) is one of the six articles of Islamic faith. It’s the day every person will be resurrected and held accountable for their deeds, with the Quran describing it as an event of overwhelming scale that ends life as it currently exists.
Qiyamah (قيامة) refers to the Day of Resurrection and Judgment, when all of creation will be raised and held accountable before Allah. It marks the end of worldly life and the beginning of eternal accountability, either in Paradise or Hellfire.
The Quran pairs belief in Allah with belief in the Last Day more often than almost any other combination of beliefs. A person’s entire framework for right and wrong, for why effort and sincerity matter, rests on the reality that this life isn’t the final measure of anything. Without accountability afterward, the Quran’s moral commands would carry a different weight entirely.
Islamic tradition describes both minor and major signs preceding the Day of Judgment. Minor signs include widespread moral decline and social change, many of which scholars describe as already unfolding gradually. Major signs are described as more dramatic and unmistakable, including the appearance of the Dajjal (a false messianic figure) and the return of Prophet Isa (Jesus, peace be upon him). The exact timing of the Day itself is described in the Quran as known only to Allah.
These aren’t separate, disconnected beliefs. Qadr establishes that a person’s choices genuinely matter and are known to Allah. Angels record those choices as they happen. Qiyamah is where that entire record is opened and accounted for. Removing any one piece changes what the other two actually mean.
Islamic teaching holds that entry into Paradise ultimately rests on Allah’s mercy, with sincere good deeds as the means, not an automatic transaction independent of that mercy.
An intermediate state called Barzakh is described in Islamic tradition, distinct from the final resurrection and judgment covered here.
Concepts of resurrection, judgment, and an afterlife appear in Christianity and Judaism as well, though the specific details, sequence of events, and theological framework in Islam are distinct.
Qiyamah closes the loop that Qadr and belief in angels open. Every choice recorded, every intention known to Allah beforehand, is accounted for in full on a single day the Quran describes as more real and more significant than the entire span of worldly life that preceded it.
