Mention of the Types of Scholars

So I say: Indeed, we have seen in this time of ours peoples who claim in themselves jurisprudence, knowledge, and Gnosis without a clear evidence nor a manifest path, and our masters, transcended their might, prohibited from that by what the advanced masters, sanctified God their souls all together, transmitted from them, so from that is what Abu al-Fath Muhammad bin Ibrahim al-Nu'mani, sanctified God his soul, narrated in the Epistle of Sincerity

[1] on the authority of al-Sadiq, transcended his might, that he said: "Indeed, among the scholars is he who loves to hoard his knowledge so it is not taken from him, so that one is in the lowest abyss of the Fire; indeed, and indeed among the scholars is he who, when he admonishes, he treats harshly, and when he rebukes, he exceeds the bounds, so that one is in the second abyss of the Fire; indeed, and indeed among the scholars is he who is seen permitting his knowledge near the possessors of wealth and honor and a place is not seen for him from the poor, so that one is in the third abyss of the Fire; indeed, and indeed among the scholars is he who goes in his knowledge the way of the tyrants and the kings,
