And on the Day when He will gather them, [it will be] as if they had not remained [in the world] but an hour of the day, [and] they will know each other. Those will have lost who denied the meeting with Allah and were not guided.
1 Mufti Taqi Usmani
The Day when He will gather them (in the next life,) they will feel as if they had not stayed (in the world) any longer than a fraction of a day. They will recognize each other. Losers, indeed, are those who deny that they will ever face Allah; they are not on the right path.
