SHAFAQNA – It is narrated from the Prophet of Islam (PBUH) who said: The most valuable people are those who have more knowledge than others; and the less valuable of them are those with less knowledge. The least enjoyable life is for the jealous person, and the least comfortable life is for the stingy one . The importance of knowledge and learning is obvious in this narration; of course this does not mean that other valuable characteristics such as piety and carrying other good deeds are ignored. If we suppose that individuals are equal in piety and morality, then the person who is more knowledgeable is more valuable. The main point in this narration is that, the Prophet of Islam (PBUH) emphasized the importance of knowledge, and also to pointed out the miserable life of jealous and stingy people.
