If we see this wonderful picture of the locust flying in the sky: it is like the gathering-together of
Doomsday:
the flying locust is like a naked man flying: these will be the associaters (who associate the Christ, the saints, the imams or other beings with God in the worship and glorification), the idolaters, the atheists and wrong-doers: they will be gathered together
naked
Quran 54: 7, which means
They will come forth from graves like locusts scattered abroad [in the space

And this aya in the Quran 18: 48; its meaning tells us that disbelievers and wrong-doers will come to the 'gathering
together' naked on Judgment Day
Now you have come to Us [naked, bare footed, without wealth or sons] as had We created you at first [when you came out of the wombs of your mothers]; and even you claimed that We should not assign an appointment to you [to be accounted with and punished

One who wants to know about the 'gathering-together' of Doomsday (Al-Mahshar); it is best explained by the interpreter of the Quran and Bible: Mohammed-Ali Hassan Al-Hilly in his book
Man after Death
