Imam Sadiq (peace be upon him): There are some scholars who love that their knowledge be stored and hoarded, and that it not be learned from them; such people are in the first level of the Fire. And there are some scholars who, whenever they are given advice, become arrogant and refuse [to accept it], and whenever they themselves give advice, they behave harshly and do not show gentleness; they are in the second level of the Fire. And there are some scholars who are seen placing knowledge with those who possess much wealth and nobility [teaching them], but are not seen saying anything to the poor and destitute [they do not benefit the poor and dervishes from their knowledge]; they are in the third level of the Fire. And there are some scholars who conduct themselves regarding their knowledge in the manner and way of tyrants and kings, and if anything of their speech is rejected [and it is said to them: your speech is false and incorrect] or there is any shortcoming in their affairs [they are not honored and shown kindness], they become angry; they are in the fourth level of the Fire. And there are some scholars who seek out the hadiths and sayings of the Jews and Christians and desire [to relate them to the people] so that their knowledge and speech may become abundant [that people may say: he is very learned and knows the sayings of every group]; they are in the fifth level of the Fire. And there are some scholars who present themselves for issuing fatwas and giving rulings [on people's questions] and say: 'Ask me [your questions],' though it is hoped [feared] that they have not grasped or found a single word [and have burdened themselves], and Allah does not love those who [know nothing yet say: we are knowledgeable, and when answering questions] burden themselves [He deprives them of His mercy]; they are in the sixth level of the Fire. And there are some scholars who acquire their knowledge for the sake of chivalry and intelligence [they gain knowledge and teach it to others so that people may count them among the chivalrous and the wise]; he too is in the seventh level of the Fire.
