Surah Yusuf, Verse 66

قَالَ لَنۡ أُرۡسِلَهُۥ مَعَكُمۡ حَتَّىٰ تُؤۡتُونِ مَوۡثِقٗا مِّنَ ٱللَّهِ لَتَأۡتُنَّنِي بِهِۦٓ إِلَّآ أَن يُحَاطَ بِكُمۡۖ فَلَمَّآ ءَاتَوۡهُ مَوۡثِقَهُمۡ قَالَ ٱللَّهُ عَلَىٰ مَا نَقُولُ وَكِيلٞ٦٦

qāla lan ur'silahu maʿakum ḥattā tu'tūni mawthiqan mina l-lahi latatunnanī bihi illā an yuḥāṭa bikum falammā ātawhu mawthiqahum qāla l-lahu ʿalā mā naqūlu wakīlun

[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."
