Saheeh International
[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."
Al-Mukhtasar fi Tafsir
Their father told them he would not send their brother with them until they had sworn by Allah that they would bring him back, unless destruction overwhelmed them all and none of them remained, and they were unable to do anything about it or to return. When they had given their father a firm promise in Allah's name, he said that Allah was a witness over what they said, and His witnessing was sufficient for them.
