Jacob's Brothers
He said, “I will not send him with you unless you swear by Allah that you will bring him back unless you are overwhelmed.” When they swore, he said, “Allah is witness to what we say.”
12:66He said: I will not send him with you till ye give me an undertaking in the name of Allah that ye will bring him back to me, unless ye are surrounded. And when they gave him their undertaking he said: Allah is the Warden over what we say.
