Al-Imam Ali (p.b.u.h), said:
Hadith n. 426
426. Amir al-mu’minin, peace be upon him, said: It does not behove a man to have trust in two positions, health and riches, because there is many a man whom you see healthy but he soon falls sick and many a man whom you see rich but soon turns destitute.
Hadith n. 427
427. Amir al-mu’minin, peace be upon him, said: Whoever complains about a need to a believer, it is as though he has complained about it to Allah; but whoever complains about it to an unbeliever it is as though he complained about Allah.
Hadith n. 428
428. Amir al-mu’minin, peace be upon him, said on the occasion of an ‘Id (Muslim feast day): It is an ‘Id for him whose fasting Allah accepts and of whose prayers He is appreciative; and (in fact) every day wherein no sin of Allah is committed is an ‘Id. 91
Hadith n. 429
429. Amir al-mu’minin, peace be upon him, said: On Judgement Day the greatest regret will be felt by man who earned wealth through sinful ways, although inherited by a person who spends it in obeying Allah, the Glorified, and will be awarded Paradise on that account while first one will go into Fire on account of it.
Hadith n. 430
430. Amir al-mu’minin, peace be upon him, said: The worst in (concluding a) transaction and the most unsuccessful in striving, is the man who exerts himself in seeking riches although fate does not help him in his aims and consequently he goes from this world in a sorrowful state while in the next world too he will face its ill consequences. 92
Hadith n. 431
431. Amir al-mu’minin, peace be upon him, said: Livelihood is of two kinds: the seeker and the sought. Therefore, he who hankers after this world death traces him till it turns him out of it; but he who hankers after the next world, worldly ease itself seeks him till he receives his livelihood from it.
Hadith n. 432
432. Amir al-mu’minin, peace be upon him, said: Lovers of Allah are those who look at the inward side of the world while others look at its outward side, they busy themselves with remoter benefits while others busy themselves in immediate benefits. They kill those things which they feared would have killed them, and leave here in this world what they think would leave them. They took amassing of wealth by others as a small matter and regarded it like losing.
They are enemies of things others love while love things which others hate. Through them, Quran has been learnt and they have been given knowledge through Quran. Through them Quran is established while through the Quran they are established. They do not see any object of hope above what they hope and no object of fear above what they fear.
