From the Science of Imam Ali part8
Imam Ali (peace be upon him) expressed on the potential scientific spirit inside him through many words, sayings and sermons. The best he said is his saying to Kumail Ibn Zeyad al-Nakhai ((O Kumail Bin Zeyad, the hearts are like vessels. The best of them is that enlightens, and keep in your mind what I am saying: people are in three: a divine scholar; a learner in the path of safety and salvation, and a savages or a riffraff followed each croaker, they lean with each wind. They did not enlighten with the light of the knowledge, and they did not resort to relevant side. The knowledge is better than money; the knowledge keeps you while you are guarding the money. The Knowledge is better than the work, and money lacks of the alimony. The love of the scholar is a religion con-demned by it; the knowledge gives the scholar an obedience in his life after his death, but the people exchange beautiful talks on him and the creature of money disappears soon he died. Those who reserve money are dead while they are alive, but the scientists are staying forever; their heads are missing and their bywords exist in the hearts, hah, that is here, and he pointed to his chest- if you get the knowledge, you will benefit, surely if you got, its understanding will be unsafe. They use the tool of the religion for the current life))
