“Once a man came to Amir al-Mu’minin, Ali ibn abu Talib (a.s.) and said, ‘O Amir al- Mu’minin, grant me good advice in the aspects of virtue so I may attain salvation.’ Amir al-Mu’minin, Ali ibn abu Talib (a.s.) said, ‘O seeker of advice, listen carefully, understand, ascertain and practice. You must know that people are of three kinds: restraining themselves from worldly matters, exercising patience and those who are inclined toward worldly gains. “From the hearts of restraining people sadness and happiness have moved out. He does not become happy for any of the worldly things, nor he is grieved over anything of the world that he may have missed, thus, he is comfortable. “The person who exercises patience has hopes to have worldly gains in his heart and when he gains anything he holds his soul back from it due to such gains’ bad consequences and disgrace. Were you to see his heart you would be astonished by its chastity, humility and determination. “To those who are inclined to worldly gains it does not matter wherefrom worldly gains come to them, lawful or unlawful as well as whether it throws filth over their honor or destroys their souls, or takes away their kindness. They are restless in a vortex. ’”
