Overall meaning :
I swear by the angels that violently snatch away the unbelievers’ souls, by the angels that gently and swiftly take away the believers’ souls, by the angels that glide throughout the heavens and the earth to carry out Allah’s commands, by the angels that hasten to obey Allah’s commands and by the angels Allah has entrusted with the task of governing whatever affairs He commands them to manage, that you, mankind, will be resurrected for judgment and recompense.
The Day when the Trumpet is blown the first time, the earth will shake violently and everyone will die, then it will be sounded again and everyone will be raised up; the hearts of the unbelievers on that day will be trembling with terror, and their eyes will be downcast in utter humiliation. Those who deny the resurrection mockingly say, ‘Will we surely be raised up alive from our graves? How can this possibly happen after we have been reduced to crumbling bones?’ ‘If we are brought back to life,’ they sarcastically add, ‘we will be losers indeed.’
It will be but one sounding of the Trumpet (the second blowing of the Trumpet), and people will all be raised up alive from their graves to be gathered on the Place of Gathering—the plains of Judgement Day!
