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

Hadith n. 457

457. Amir al-mu’minin, peace be upon him, said: Two greedy persons never get satiated, the seeker of knowledge and the seeker of this world.

Hadith n. 458

458. Amir al-mu’minin, peace be upon him, said: Belief means you should prefer truth when it harms you rather than falsehood when it benefits you; your words should not be more than your action and you should fear Allah when speaking about others.

Hadith n. 459

459. Amir al-mu’minin, peace be upon him, said: Destiny holds sway over (our) predetermination till effort itself brings about ruin.

As-Sayyid ar-Radi says: Something of this meaning has already appeared earlier though in words different from these.

Hadith n. 460

460. Amir al-mu’minin, peace be upon him, said: Forbearance and endurance are twins and they are the product of high courage.

Hadith n. 461

461. Amir al-mu’minin, peace be upon him, said: Backbiting is the tool of the helpless.
