The people of the exoteric interpret Ya'qub's saying “and I know from Allah that which you do not know” to mean that Yusuf's vision was true and a revelation—meaning that his vision concerning the prostration of the sun, the moon, and the stars to him would come to pass. Yet, this interpretation does not fall outside the framework of speaking about Yusuf,
and Ya'qub's knowledge of him and from him, which his brothers did not know. So let the reader reflect.
The Seventh Verse: He said: [“He said, 'No blame will there be upon you today. Allah will forgive you; and He is the most merciful of the merciful.'”] 1
The pronoun in “upon you” refers to the brothers of Yusuf, and the one addressing them with his saying “no blame will there be upon you”—meaning no reproach and no censure upon you—is our master Yusuf. In this is an allusion that he is Allah who forgives them, by virtue of his pardoning them and his refraining from punishing them in exchange for what appeared from them toward him of hatred and envy, according to the exoteric appearance (hasab al-zahir).
The Eighth Verse: [“Take this, my shirt, and cast it over the face of my father; he will become seeing. And bring me your family, all together.”] 2
