How do people transition from the Earth to the Sirat after the Resurrection, the taking of the Books and the Scale, and the scattering of the scrolls? And how do they transition from after the Sirat to Paradise?

On the Day when the earth is changed to other than the earth, and the heavens, people will be either on the Sirat (Bridge) or in the darkness before it. This new earth will be another, white, pure land, like silver, with no landmarks or crookedness, stretched out like the tanned hide of Ukaz. It may also be the same earth, but its characteristics are changed; its mountains and valleys are removed, and it is stretched out.
