And when he mentioned the two verses, he mentioned what they are. He began with them because there is no righteousness for it except with them, just as there is no righteousness for the body except with the soul and the intellect. He said: "And the day" meaning by that which is the place of spreading in what the decrees have occurred. "When it shines" meaning it has illuminated the sun with a great adornment, some of which is greater than others in terms of length and shortness, clarity and cloudiness, mist and clarity. Just as the bodies sometimes purify the hearts and souls and intellects, and sometimes they defile them. This is because the intellect can be in the utmost clarity and calling to good in the state of youth, then it continues to increase and decrease according to the purity of the body in good nature or its impurity due to bad nature, until the person becomes pure light, a speaking king when the body matches the intellect, and they cooperate in good. Or he becomes pure darkness, a cursed devil when the body opposes the intellect due to bad nature and the evil of temperament.
