قَالَ لَنۡ أُرۡسِلَهُۥ مَعَكُمۡ حَتَّىٰ تُؤۡتُونِ مَوۡثِقًا مِّنَ ٱللَّهِ لَتَأۡتُنَّنِى بِهِۦٓ إِلَّآ أَن يُحَاطَ بِكُمۡ ۖ فَلَمَّآ ءَاتَوۡهُ مَوۡثِقَهُمۡ قَالَ ٱللَّهُ عَلَىٰ مَا نَقُولُ وَكِيلٌ
(Jacob) said: "Never will I send him with you until ye swear a solemn oath to me, in Allah's name, that ye will be sure to bring him back to me unless ye are yourselves hemmed in (and made powerless). And when they had sworn their solemn oath, he said: "Over all that we say, be Allah the witness and guardian!"<br/>
He said, 'I will not send him with you until you give me a [solemn] pledge, a covenant, in the name of God, by your swearing an oath, that assuredly you will bring him back to me, unless you are besieged', such that you die, or are overwhelmed and thus unable to bring him back. They agreed to this. And when they gave him their [solemn] pledge, to this effect, he said, 'God shall be Guardian, Witness, over what we say', we and you. Thus he sent him with them.
