Hz Ali said

. I want to teach you five of those things which deserve your greatest anxiety to acquire them: Have hope only in Allah. Be afraid of nothing but sins. If you do not know a thing never feel ashamed to admit ignorance. If you do not know a thing never hesitate or feel ashamed to learn it. 
Acquire patience and endurance because their relation with true faith is same a head to a body, a body is  not usefully without a head, similarly true faith can be  not use without attributes of resignation, endurance and patience.

hz Ali (r.a)
