Resurrection(Qayamat).
The entire universe will remain destroyed till Allah wishes. Someone asked Ma'soom (A.S.) regarding this time gap. Ma'soom (A.S.) replied that, "It will remain like that
for forty years". In another tradition it is stated that "It will remain like this for four hundred years". Thereafter it will rain consequently for forty days and all physical matter will gather together and collect. Israfeel will be the first one to come to life again. Allah will then command him to blow the trumpet again, he shall do so and all dead will arise. A voice will then come "0 souls driven forth from the bodies!
and the scattered flesh! and the rotten bones! and the dispersed hairs, come and join together, come forth to account (for your deeds)".
The earth will be commanded by Allah to vomit all that lies buried in it. "And the earth brings forth her burdens". (Surah-az-Zilzal: 2)
All the matter buried in the earth will come out and join. And the people will arise and stand together. But each one will have a distinct state and different voices. The virtuous will be uttering Allah's praises "Praise be to Allah who has fulfilled what He promised". While the sinners Will be lamenting while coming out of their graves "O
woe to us!who has raised us up from our sleeping place". (Surah-al Yaseen: 52)
