And Joseph's brethren came and presented themselves before him, and he knew them but they knew him not. 58 When he had furnished them with provisions, he said, "Next time, bring me your other brother from your father. As you can see, I give each of you a certain amount of grain; I am a polite host. 59 But if you do not bring him to me, you shall have no grain from me, nor shall you ever approach me again." 60 Joseph's brothers said, "We shall try to influence his father to send him with us and we shall be successful". 61 And Joseph said to his servants: "Put surreptitiously in their packs the goods they had given in exchange for corn." Joseph did so expecting that they would find it when they returned home. Feeling grateful for this generosity, they might be inclined to return to him. 62 When they returned to their father they said: "Father! We have been denied further supply of corn. So send with us our brother that we may bring the supplies. We shall be responsible for his protection." 63 Jacob replied, "How can I trust you after what happened to his brother before? Only God is the best Protector. His mercy is far greater than that of others." 64 And when they opened their bags, they found their money had been returned to them. They said: "O our father! What (more) can we desire? This, our money has been returned to us, so we shall get (more) food for our family, and we shall guard our brother and add one more measure of a camel's load. This quantity is easy (for the king to give)." 65 (Jacob) said: "Never will I send him with you until ye swear a solemn oath to me, in Allah's name, that ye will be sure to bring him back to me unless ye are yourselves hemmed in (and made powerless). And when they had sworn their solemn oath, he said: "Over all that we say, be Allah the witness and guardian!" 66 (As they were leaving) their father said to them: "O my sons, do not seek one approach but employ different ways (of attaining your object). If anything should befall you from God I shall not be able to avert it, for all authority belongs to God. I have placed my trust in Him, and the trusting should rely on Him alone." 67 And when they entered according to their father's advice, it did not avail them in the least against (the Will of) Allah, it was but a need of Ya'qub's (Jacob) inner-self which he discharged. And verily, he was endowed with knowledge because We had taught him, but most men know not. 68
