It is narrated from Imam Ali (AS) who said: O’ Jabir, the world stands on four points.
1.The wise person who makes practical and effective use of his/her knowledge.
2.The ignorant who refuses to learn.
3.The charitable person who does not refrain from donating.
4.And the poor who does not sell (exchange) his/her hereafter for the sake of the world.
Therefore, if the wise ignores his /her knowledge and the ignorant refuses to learn, and the rich refrain from donating and the poor sells his/her hereafter to the world; then the stability of the society disappears. O’ Jabir, the people’s need to the one who enjoys many of God’s blessings is greater; therefore, whoever works for the sake of God with those blessings, God will make those blessings to last; and the one who does not utilize those blessings properly, God will take them away [1]. In another narration, Imam Ali (AS) said: What makes people to be unwilling to seek knowledge is that they see a lot of those scholars who do not act upon their knowledge [2].
