When the earth is shaken to her (utmost) convulsion,
To the ordinary human observer a violent
earthquake is a terrifying phenomenon, in its
suddenness, in its origin, and in its power to destroy and
uproot the strongest buildings and to bring up strange
materials from the bowels of the earth.
The Overwhelming Event (Surah 88) which ushers in the
Judgment will be a bigger and more far-reaching
convulsion than any earthquakes that we know. And yet
the incidents of earthquakes may give us some idea of
that supreme world-shaking Event.
