And the earth is moved, and its mountains,(5649) and they are crushed to powder at one stroke,-
5649 The whole of our visible world, as we now know it, will pass away, and a new world will come into being. The mountains are specially mentioned, because they stand as a type of hardness, size, and durability. They will be "crushed to powder", i.e., lose their form and being at one stroke (Cf. 89:21).
