Allah informs of the horrors that will take place on the Day of Judgement. The first of these events is the blowing of fright (into the Trumpet), which will be followed by the blowing of destruction when everyone in the heavens and the earth will be struck down except whoever Allah wills. Then, after this will be the blowing of standing before the Lord of all that exists, and the resurrection, and the gathering. And this is that blowing. It is emphasized here that it is one blowing, because the command of Allah cannot be opposed or prevented, and it does not need to be repeated or stressed. Thus, Allah goes on to say,

﴿وَحُمِلَتِ الاٌّرْضُ وَالْجِبَالُ فَدُكَّتَا دَكَّةً وَحِدَةً ﴾

(And the earth and the mountains shall be removed from their places, and crushed with a single crushing.) meaning, they will be stretched out to the extent of the surface (of the earth) and the earth will change into something else other than the earth.

﴿فَيَوْمَئِذٍ وَقَعَتِ الْوَاقِعَةُ ﴾

(Then on that Day shall the Event occur.) meaning, the Day of Judgement.

﴿وَانشَقَّتِ السَّمَآءُ فَهِىَ يَوْمَئِذٍ وَاهِيَةٌ ﴾

(And the heaven will be rent asunder, for that Day it will be frail and torn up.) Ibn Jurayj said, "This is like Allah's statement,

﴿وَفُتِحَتِ السَّمَآءُ فَكَانَتْ أَبْوَباً ﴾

(And the heaven shall be opened, it will become as gates.) (78:19) Ibn `Abbas said, "It (the sky) will be torn apart and the Throne will be near it.''

﴿وَالْمَلَكُ عَلَى أَرْجَآئِهَآ﴾

(And the angels will be on its sides,) The word Malak here is referring to the species of angels (all of them); meaning the angels collectively will be standing on the sides of the heavens. Ar-Rabi` bin Anas said concerning Allah's statement,

﴿وَالْمَلَكُ عَلَى أَرْجَآئِهَآ﴾

(And the angels will be on its sides,) "This means that they will be standing on what has been ground to powder of the heavens looking at the people of the earth.'
