And His words: (And the mountains are set in motion and become a mirage) — He says: And the mountains are blown apart and torn out by their very roots from their foundations, and so changed into scattered dust, in the eyes of whoever looks on, like the mirage (as-sarāb) which whoever sees it from afar supposes to be water, while in reality it is dust.
