HKB”H will offer the goyim the chance to do one mitzvah and get reward – and he will choose the Mitzvah of Sukkah. The Nations of the World will build sukkas. At this point, Hashem will remove the sun from it’s sheath, and each of them will kick their sukkah and leave.
“Removing the sun from it’s sheath” – at least in the simplest understanding – refers to the strengthening of the sun, not the sun disappearing. (See also Nedarim 8b.)
