One day, a mysterious prophet told the world, “In a few days, all water throughout the earth from natural sources will disappear and be replaced with new water that will make people crazy when they drink it. However, any water that is specially stored will not undergo this transformation.”
Only a man named Hasan paid attention to this, and he gathered water and stored it in anticipation of the change.
Three days later, just as the prophet said, the water from natural sources stopped running and was replaced by the new type of water.
Everybody drank the new water except for Hasan, who had saved and specially stored the original water. And soon Hasan noticed that all the people began acting differently and that they had no knowledge of the prophet’s prophecy or of the day that the waters were changed.
When Hasan began interacting with the people they thought that he was crazy, and they ostracized him.
Hasan continued to drink his stored water for a few more weeks, but he could not take the loneliness anymore, and he decided to drink the new water and become like everyone else.
From then on, the people regarded Hasan as a former madman who had his sanity renewed.
