O people, eat of what is in the earth [lawful and wholesome; and follow not the steps of Satan; he is a manifest foe to you]: that is, partake in the pleasures and the enjoyments that are in the lower direction of the world of the soul and the body in a manner that is lawful and wholesome, that is to say, according to the law of moderation as permitted by the Law and as sanctioned by the intellect in the measure that is needed and is necessary. And do not transgress the limit of moderation, within which these [pleasures and enjoyments] are wholesome and beneficial, into the bounds of immoderation, for these are the footsteps of Satan, which is why God says: Indeed squanderers are brothers of devils [Q. 17:27]. For he [Satan] is an enemy to you, [one] whose enmity is clear; he desires to lead you to perdition and make you odious in the eyes of your Lord by your committing of reprehensible acts of immoderation, as He [God] does not love the immoderate. Know that enmity in the world of the soul corresponds to the shadow of familiarity (ulfa) in the world of the heart, while moderation is its shadow in the world of the body. Familiarity is the shadow of love in the world of the spirit, the latter being the shadow of true Oneness. Thus moderation is the fourth shadow of the Oneness and Satan flees from the shadow of the Truth, unable to endure it, he is forever stepping from the realm of these shadows into the side of immoderation, and if he is unable, then to the side of excess, as happens in the case of love and familiarity; which is why the commander of the believers ʿAlī, peace be upon him, said: 'You find that the ignorant is [one of two], either excessive or prodigal'. Verily the ignorant person is the laughingstock of Satan.
