The Horrors of the Day of Resurrection
فَإِذَا انشَقَّتِ السَّمَاء
Then when the heaven is rent asunder,
on the Day of Resurrection; this meaning is clear in this and similar Ayat, such as,
وَانشَقَّتِ السَّمَأءُ فَهِىَ يَوْمَيِذٍ وَاهِيَةٌ
And the heaven will be rent asunder, for that Day it (the heaven) will be frail and torn up. (69;16),
وَيَوْمَ تَشَقَّقُ السَّمَأءُ بِالْغَمَـمِ وَنُزِّلَ الْمَلَـيِكَةُ تَنزِيلً
And (remember) the Day when the heaven shall be rent asunder with clouds, and the angels will be sent down, with a grand descending. (25;25)
إِذَا السَّمَأءُ انشَقَّتْ
وَأَذِنَتْ لِرَبِّهَا وَحُقَّتْ
When the heaven is split asunder, and listens to and obeys its Lord -- and it must do so. (84;1-2)
فَكَانَتْ وَرْدَةً كَالدِّهَانِ
and it becomes Wardah like Dihan.
This means they will melt just as sediment and silver are melted when heated. And they will be colored, just as dies stain something, sometimes red, sometimes yellow, or blue, or green. This demonstrates the extent of the horrors of the Mighty Day of Resurrection.
As-Suddi said, "It will be as rosy color and as filth oil."
(like Dihan), "Like the colors of dyes."
فَبِأَيِّ الَاء رَبِّكُمَا تُكَذِّبَانِ
