[2/8] al-Khisal: From his father (i.e. Ali b. al-Husayn b. Babawayh) from Sa’d b. Abdallah from Ahmad b. Abi Abdillah al-Barqi from al-Hasan b. Ali b. Fadhal from Tha’laba b. Maymun from Abi Abdillah عليه السلام who said: the commander of the faithful عليه السلام said: men are of three kinds: intelligent, foolish and corrupt sinner, as for the intelligent one the religion is his path, and forbearance is his habit, and giving counsel is his disposition, when he is asked he answers, and when he speaks he is to the point, and when he hears he comprehends, and when he reports he is truthful, and when one confides in him he is loyal, as for the fool if someone alerts him to a beautiful thing he overlooks it, and if he is dissuaded from good he acquiesces to forsake it, and if he is driven to ignorance he becomes ignorant, and if he reports he is incorrect, he does not understand and if perchance he is able to understand he does not learn from it, and as for the corrupt sinner if you rely on him he betrays you, and if you befriend him he hates you, and if you trust him he is not sincere with you.
[1/7] Usul al-Kafi: Muhammad b. Yahya from Ahmad b. Muhammad from Ibn Mahbub from Abdallah b. Sinan who said: I mentioned a person who was afflicted by forgetfulness in Wudhu and Salat to Abu Abdillah عليه السلام and added: He is a person with intellect. Abu Abdillah عليه السلام said: and what kind of intellect does he have while he is obeying Satan? I said to him: how is he obeying Satan? he said: ask him – this that comes over him what is its cause? he will tell you it is from the handiwork of Satan.
