Prepare oneself for the Day of Judgment by doing good deeds & avoiding sins; strive to please Allah SWT; remember that our actions now determine our fate on this day; enter Paradise instead of Hellfire

On the Day of Judgment, all people will be gathered together in a single place. They will not have any clothing or footwear on them and they won't have been circumcised either. This is an indication that this day is so serious that no one would even think about looking at each other in such a state. It also shows how important it is for us to prepare ourselves for this day by doing good deeds and avoiding sins so we can enter Paradise instead of Hellfire. We should remember that our actions now determine our fate on this day and strive to do what pleases Allah SWT so we can receive His mercy on that day.
