“Ha! There is nothing else to be done,” thought Idris. “The hurricane has delayed our pursuers also, and as soon as it ceases we will gallop once more toward the south.”
So he cried out for them to remount. But just then something happened that completely changed the situation. The dark sand-clouds, now almost jet black, were suddenly permeated with bluish light. Then the darkness grew still more intense, and now arose in the higher regions of the air the slumbering thunder. Awakened by the whirlwind, it began to roll loudly, threateningly, and angrily between the Arabian and Libyan deserts. It seemed as if mountains were falling from the sky. The deafening noise increased; it made the earth tremble, and began to encircle the entire horizon.[7] From time to time the sound crashed with such terrible force that it seemed as though the firmament was broken and falling to earth. Sometimes it was like a hollow, distant rumbling; then again it broke forth still louder, flashed its blinding lightning, threw thunderbolts, rose and fell and crashed again. This continued a long while.

At last came the first large raindrops that generally follow a hurricane, and the leader shouted through the darkness:
