Abu Ja’far Ibne Jarir Tabari has narrated through his authorities from Jabir that he said:
Once, I saw Imam Hasan (a) soar up into the atmosphere and disappear in the sky and remain there for three hours continuously. Then he descended from there calmly and in dignity. I said: May my parents be sacrificed on you, you achieved whatever you wanted.
