(79:6) The Day when the quaking will cause a violent convulsion,
يَوۡمَ تَرۡجُفُ الرَّاجِفَةُ ۙ
(79:7) and will be followed by another quaking.2 تَتۡبَعُهَا الرَّادِفَةُ ؕ
(79:8) On that Day some hearts shall tremble (with fright),3 قُلُوۡبٌ يَّوۡمَٮِٕذٍ وَّاجِفَةٌ ۙ
(79:9) and their eyes shall be downcast with dread.
اَبۡصَارُهَا خَاشِعَةٌ ۘ
2. The first jolt implies the jolt which will destroy the earth and everything
on it, and the second jolt at which all dead men will rise up from death and
from their graves. This same state has been described in Surah Az-Zumar, thus:
And when the Trumpet shall be blown on that Day, all those who are in the heavens
and the earth shall fall down dead except those whom Allah may allow (to live).
Then the Trumpet shall be blown again and they will all stand up, looking around.
3. Hearts shall tremble: because, according to the Quran, only the disbelievers,
the wicked people and the hypocrites will be terror-stricken on the Resurrection
Day, the righteous believers will remain secure from this terror. About them
in Surah Al-Anbiya (verse 103) it has been said: The time of great fright will
not trouble them at all; the angels will rush forth to receive them, saying:
This is the very day which you were promised.
