[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."

He [Ya‘qûb (Jacob)] said: "I will not send him with you until you swear a solemn oath to me in Allâh’s Name, that you will bring him back to me unless you are yourselves surrounded (by enemies)," And when they had sworn their solemn oath, he said: "Allâh is the Witness to what we have said."
