Assembly: This occurs after Resurrection. The people will be gathered at a place to be questioned about their deeds. This place is the changed Earth. This Earth that we are on now will be changed on the Day of Judgment to a flat Earth with no mountains or valleys. 

 The assembled people are in three categories: 

The first type will be assembled fed, riding, and dressed. These people are the pious Muslims who were in this life performing the obligations and avoiding the sins. 

The second type will be assembled barefoot and naked. These are the Muslim major sinners. 

The third and final type will be assembled and dragged on their faces. These are the blasphemers.  

It was mentioned concerning the torture of the arrogant people that they would be gathered having the size of ants but the shape of humans. As an insult, the other people will step on the arrogant people, but they will not die.
