Then when they despaired of him, they retired, conferring privately together. The eldest of them said: Do you not know that your father took from you a covenant in Allah's name, and how you fell short of your duty with respect to Yusuf before? Therefore I will by no means depart from this land until my father permits me or Allah decides for me, and He is the best of the judges: 80 Return unto your father and say: O our father! Lo! thy son hath stolen. We testify only to that which we know; we are not guardians of the Unseen. 81 Inquire of [the people of] the city where we lodged, and of the caravan with which we travelled. We are telling you the truth.'" 82 Jacob said, "No, but you have yourselves contrived a story. But it is best to be patient. God may well bring them all back to me [in the end]. For He is indeed full of knowledge and wisdom." 83 And he turned away from them and said: "Alas, my grief for Yusuf (Joseph)!" And he lost his sight because of the sorrow that he was suppressing. 84 They said, “By Allah, you will keep remembering Yusuf till your health fails you or you lose your life.” 85 He said "I only complain of my anguish and my sorrow to God. God has made known to me things that you do not know. 86 Go, my sons, and seek news of Joseph and his brother. Do not despair of God's mercy; none but those who deny the truth despair of God's mercy." 87 And when they came (again) before him (Joseph) they said: O ruler! Misfortune hath touched us and our folk, and we bring but poor merchandise, so fill for us the measure and be charitable unto us. Lo! Allah will requite the charitable, 88 He said, "Do you know what you did with Joseph and his brother when you were ignorant?" 89 They said, 'Why, art thou indeed Joseph?' 'I am Joseph,' he said. 'This is my brother. God has indeed been gracious unto us. Whosoever fears God, and is patient -- surely God leaves not to waste the wage of the good-doers. 90 They said: "By Allah! indeed has Allah preferred thee above us, and we certainly have been guilty of sin!" 91 He said: "No reproach on you this day, may Allah forgive you, and He is the Most Merciful of those who show mercy! 92 [And now] go and take this tunic of mine and lay it over my father's face, and he will recover his sight. And thereupon come [back] to me with all your family." 93
