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

Hadith n. 421

421. Amir al-mu’minin, peace be upon him, said: It is enough if your wisdom distinguishes for you the path of your going astray from the path of your guidance.

Hadith n. 422

422. Amir al-mu’minin, peace be upon him, said: Do good and do not regard any part of it small because its small is big and its little is much. No one of you should say that another person is more deserving than I in doing good. Otherwise, by Allah, it would really be so. There are people of good and evil. When you would leave either of the two, others will perform them.

Hadith n. 423

423. Amir al-mu’minin, peace be upon him, said: Whoever set right his inward self, Allah sets right his outward self Whoever performs acts for his religion, Allah accomplishes his acts of this world. Whoever’s dealings between himself and Allah are good, Allah turns the dealings between him and other people good.

Hadith n. 424

424. Amir al-mu’minin, peace be upon him, said: Forbearance is a curtain for covering, and wisdom is a sharp sword. Therefore, conceal the weaknesses in your conduct with forbearance and kill your desires with your wisdom.

Hadith n. 425

425. Amir al-mu’minin, peace be upon him, said: There are some creatures of Allah whom Allah particularizes with favours for the benefit of the people, therefore He places them in their hands so long as they give them to others; but when they deny them to others He takes away the favours from them and sends them to others.
