Al-Imam Ali (p.b.u.h), said:
Hadith n. 390
390. Amir al-mu’minin, peace be upon him, said: The believer’s time has three periods: The period when he is in communion with Allah; the period when he manages for his livelihood; and the period when he is free to enjoy what is lawful and pleasant. It does not behove a wise person to be away (from his house) save for three matters, namely for purposes of earning, or going for something for the next life or for enjoying what is not prohibited.
Hadith n. 391
391. Amir al-mu’minin, peace be upon him, said: Abstain from the world so that Allah may show you its real evils and do not be neglectful because (in any case) you will not be neglected.
Hadith n. 392
392. Amir al-mu’minin, peace be upon him, said: Speak so that you may be known, since man is hidden under his tongue.
Hadith n. 393
393. Amir al-mu’minin, peace be upon him, said: Take off the favours of the world whatever comes to you and keep away from what keeps away from you. If you cannot do so be moderate in your seeking.
Hadith n. 394
394. Amir al-mu’minin, peace be upon him, said: Many an expression is more effective than an attack.
Hadith n. 395
395. Amir al-mu’minin, peace be upon him, said: Every small thing that is contented upon, suffices.
