And when they opened their baggage, they found their merchandise returned to them. They said, "O our father, what [more] could we desire? This is our merchandise returned to us. And we will obtain supplies [i.e., food] for our family and protect our brother and obtain an increase of a camel's load; that is an easy measurement."
[Jacob] said, "Never will I send him with you until you give me a promise [i.e., oath] by Allāh that you will bring him [back] to me, unless you should be surrounded [i.e., overcome by enemies]." And when they had given their promise, he said, "Allāh, over what we say, is Entrusted."
And when they entered from where their father had ordered them, it did not avail them against Allāh at all except [it was] a need [i.e., concern] within the soul of Jacob, which he satisfied. And indeed, he was a possessor of knowledge because of what We had taught him, but most of the people do not know.
