I found this from Imam Zaid’s blog.
“It is related that a devout worshipper by the name of Humam came to Imam ‘Ali, may God ennoble his countenance, and asked him to describe the God conscious people so vividly that he could almost see them. Imam ‘Ali responded: “Their speech is truthful; their clothing is moderate; and they walk with utmost humility. They lower their gaze from everything God has forbidden. They allow their ears to listen only to that which is beneficial. Their souls accept exposure to trials and tribulations [in adherence to the truth] as easily as others accept luxurious living. Were it not for their appointed term, their spirits would not have remained in their bodies the span of a twinkling of the eye due to their intense longing for their Lord. Because the Creator is magnified in their souls, everything else is viewed as insignificant in their sight. Their hearts are sober; people are safe from any wickedness from them; their bodies are slim [they don’t overindulge their appetites]; their basic needs are few; and their souls are chaste. They patiently endure the few days they spend in this world knowing that they will be followed by a long, peaceful rest—this is the profitable life-transaction which their Lord has allowed them to enter into. The world desired them; however, they had no desire for it. It imprisoned them, but they ransomed their souls from it [with their restraint and righteous deeds].”
