Believers adopt Hazrat Mahdi's (as) moral virtue as a role model

He attains Divine virtue. He receives knowledge of the faith and exemplary moral virtue from Allah. (Al-Qunawi, Risalat al-Mahdi, p. 161 B)

In the Qur’an it is revealed that our Prophet (saas) is the finest possible role model for true believers:
 

You have an excellent model in the Messenger of Allah, for all who put their hope in Allah and the Last Day and remember Allah much. (Surah al-Ahzab, 21)
