Surah 99. Az-Zalzalah, Ayah 1

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 (S. lxxxviii.) 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.
