During my long friendship with Hisham b. al-Hakam, I have not heard nor benefited from anything more than I did from these words regarding the immaculate nature of the Imam. One day, I asked him about the Imam: is he immaculate? So Hisham said: Yes. So, I said: So, what is the description of his immaculateness? And how is it recognized? Hisham said: Surely, all sins are due to the following four, and there is no fifth: greed, jealousy, anger, and lust. None of these exist in an Imam. An Imam cannot be greedy toward this world while it is [all] under his ring, for he is the treasurer of the Muslims. So why should he be greedy? An Imam cannot be jealous, since man would be jealous of what is above him, not what is lower than him. However, there is no one higher than an Imam. So how could he be jealous of anyone who is lower than himself? An Imam cannot get angry at any worldly affairs unless it be for what angers Allah. Allah has made him responsible in establishing the limits. Thus, he becomes angry at the blamers, and he befriends others for their religion, so that the limits of Allah are established. An Imam cannot follow lusts, since he has already preferred the Hereafter over this world. Surely, Allah has made the Hereafter beloved to him, just as He made this world beloved to us. So, he looks to the Hereafter the way that we look at this world. Have you seen anyone who abandoned a beautiful face for an ugly face, or tasty food for bitter food, or soft clothes for rough clothes? Everlasting blessings are for the everlasting world, while this world is transient and fleeting.
