Hazrat Mahdi's (as) followers will be very select

The hadith states that Hazrat Mahdi’s followers will be well educated individuals. One reason why Hazrat Mahdi’s (as) followers being well educated is a distinguishing feature is that people in their day will not exhibit nobility, courtesy or moral virtue. This will make the followers of Hazrat Mahdi (as) highly select individuals in the society they live in.  

The followers of Hazrat Mahdi (as) will be noble and well educated. (Al-Malaahem wa al-Fetan, p. 205)
