Story of Prophet Yusuf (AS) Part -26

The Return
Yousif went to oversee supplying his brothers
with wheat. Then he ordered the Wheat Official
to put the silver dirhams secretly in the
containers of his brothers.
Yousif understood that his brothers led a poor
life. Thus, he returned their dirhams to them
and did not tell them about it.
Yousif came to see his brothers off. Then he
asked them: "Are you satisfied with the
measure."
"Yes, we are," they replied.
Then Yousif requested: "When you come to
Egypt, bring me your brother Benyamin. When
you bring him, we'll add a measure to your
share. If you don't bring him, don't come to
Egypt."
One of them said: "We'll do our best to
persuade his father to allow him to come with
us."
Yousif's ten brothers went back to the land of
al-Khalil. They told their father about what
had happened. They said to him: "The Chief of
Egypt (Yousif) won't supply us with wheat if
we don't take Benyamin with us."
Ya'qub said: "I cannot trust in you with
respect to him, except as I trusted in you with
respect to his brother before; but Allah is the
best Keeper, and He is the most merciful of
the merciful ones."
Ya'qub wept. He remembered Yousif, who had
disappeared for twenty years.
When the ten brothers opened their goods,
they found their money returned to them. They
rejoiced very much. Thus, they came back to
their father to give him the good news, saying:
"Father, shall we request more than this? Our
money has been returned to us with the
wheat. So send our brother with us to bring
wheat to our family. We will guard our brother
and have an additional measure of a camel-
(load)."
Ya'qub said: I will not send him with you until
you give me a firm covenant from Allah that
you will bring him to me, unless you are
completely surrounded."
The ten brothers promised their father to take
care of their brother Benyamin.
