Quran 12:65 — Joseph (Yousuf)

When they opened their bags, they found their goods returned to them. They said, "Our father, what more can we ask for? Here are our goods returned to us. We can thus provide for our family, protect our brother, and receive one more camel-load. This is certainly a profitable deal."

[12:64] He said, "Shall I trust you with him, as I trusted you with his brother before that? GOD is the best Protector, and, of all the merciful ones, He is the Most Merciful."

[12:66] He said, "I will not send him with you, unless you give me a solemn pledge before GOD that you will bring him back, unless you are utterly overwhelmed." When they gave him their solemn pledge, he said, "GOD is witnessing everything we say."
