When would the souls be reunited with the regenerated human bodies in the graves?

Verses 1-14 of Chapter 81:
When the sun is folded up, and when the stars scatter, and when the mountains are set in motion, and when the ten month pregnant she-camels are left untended, and when the beasts are gathered together, and when the oceans are set ablaze, and when the souls are reunited (with their bodies), and when the infant girl, buried alive, is asked for what crime she was slain, and when the records are unfolded, and when the veil of heaven is removed,and when Hell is set blazing, and when Paradise is brought near, then each person shall know what he has brought with him.

Verses 1-5 of Chapter 82:
When the heaven is cleft asunder, and when the stars scatter, and when the seas are torn apart, and when the graves are laid open. Then every person shall know all his works, the former and the latter.
