“Once I went to see abu Ja’far (a.s.) to say farewell. He said, ‘O Khaythamah, convey our greeting of peace to whoever of our followers you may see and advise them to be pious before Allah, the Most Great, that their rich ones look after their poor ones, the stronger ones look after their weaker ones, that the living attend the funeral of those who have just died, that they must meet each other in their homes; their meeting as such is life for our cause. May Allah bless the man who preserves our cause. O Khaythamah, inform our followers that we cannot make them independent of Allah in anything without good deeds and that they will not benefit from our Divine Authority without ( al-Wari ’) refraining from worldly attractions (sins). Of the people who regret on the Day of Judgment, most intensely will be the ones who describe justice but do not practice it (explain the right belief but do not establish one).”’
