Al-Imam Ali (p.b.u.h), said:

Hadith n. 112:
Whoever loves us, members of the Household (of the Prophet), should be prepared to face destitution.

As-Sayyid ar-Radi says: This has been interpreted in a different way as well, but on this occasion is not fit to mention here.

Hadith n. 113:
Amir al-mu’minin, peace be upon him, said: No wealth is more profitable than wisdom, no loneliness is more estranging than vanity, no wisdom is as good as tact, no honour is like fear from Allah, no companion is like the goodness of moral character, no inheritance is like civility, no guide is like promptitude, no trade is like virtuous acts, no profit is like Divine reward, no self-control is like inaction in time of doubt, no abstention is like that (which is) from prohibitions, no knowledge is like thinking, no worship is like the discharge of obligation, no belief is like modesty and endurance, no attainment is like humility, no honour is like knowledge, no power is like forbearance, and no support is more reliable than consultation.

Hadith n. 114:
Amir al-mu’minin, peace be upon him, said: At a time when virtue is in vogue in the world and among people, if a person entertains an evil suspicion about another person from whom nothing evil has ever been seen, then he has been unjust. And at a time when vice is in vogue in the world and among people, if a man entertains a good idea about another person he has flung himself in peril.
