قَالَ لَنْ اُرْسِلَهٗ مَعَكُمْ حَتّٰى تُؤْتُوْنِ مَوْثِقًا مِّنَ اللّٰهِ لَتَأْتُنَّنِيْ بِهٖٓ اِلَّآ اَنْ يُّحَاطَ بِكُمْۚ فَلَمَّآ اٰتَوْهُ مَوْثِقَهُمْ قَالَ اللّٰهُ عَلٰى مَا نَقُوْلُ وَكِيْلٌ ( يوسف: ٦٦ )

Sahih International:
[Jacob] said, "Never will I send him with you until you give me a promise [i.e., oath] by Allah 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, "Allah, over what we say, is Entrusted." (Yusuf [12] : 66)
1 Mufti Taqi Usmani
He said, “I shall never send him with you until you give me a pledge in the name of Allah that you will definitely bring him back to me, unless you are overpowered (by circumstances).” So, when they gave him their pledge, he said, “Allah is watchful over what we say.”
