The earth is resting on the horns of a great bull. When he shakes his head he brings earthquakes.

(Ibne Kathir 2:29, 50:1).




Then Ibne Kathir changes his mind: The earth is resting on a fish. The fish is resting on water, water on the Mount Safa in Makkah, Safa on an angel, the angel on a rock, the rock on air. When the fish moves, it causes earthquakes.

(Imam Ibne Kathir, Tafseer part I pg 76)
