Hazrat Mahdi's (as) followers will have no material or spiritual interest in worldly things

O Abu Hurairah! This community [THE COMMUNITY OF HAZRAT MAHDI (AS)] will achieve the degree of the prophets by embarking on a hard and difficult road. THEY WILL CHOOSE HUNGER ONCE ALLAH HAS FED THEM, NAKEDNESS AFTER HE HAS CLOTHED THEM, AND THIRST AFTER HE HAS GIVEN THEM TO DRINK; THEY WILL PLACE THEIR HOPES IN ALLAH AND ABANDON THESE. THEY WILL EVEN ABANDON WHAT IS LAWFUL OUT OF FEAR OF HIS RECKONING. THEY WILL SHOW INTEREST IN THIS WORLD ONLY WITH THEIR BODIES, AND THEY WILL OCCUPY THEMSELVES WITH NOTHING BELONGING TO IT.

Even the angels and the prophets will be amazed at their obedience to our Lord. How happy they are! How happy they are! How I would have wished to see Allah unite me and them! ... (Ibn al-Arabi, Al-Wasaya , no: 198/2, p. 486a)
