Quran 12:66 from Surah Yusuf on Divine Marvels.
قَالَ لَنۡ أُرۡسِلَهُۥ مَعَكُمۡ حَتَّىٰ تُؤۡتُونِ مَوۡثِقٗا مِّنَ ٱللَّهِ لَتَأۡتُنَّنِي بِهِۦٓ إِلَّآ أَن يُحَاطَ بِكُمۡۖ فَلَمَّآ ءَاتَوۡهُ مَوۡثِقَهُمۡ قَالَ ٱللَّهُ عَلَىٰ مَا نَقُولُ وَكِيلٞ
English translation: He said Never will I send him with you until you give to me a promise by Allah that surely you will bring him to me that surely you will bring him to me unless that you are surrounded you are surrounded And when they had given him their promise he said Allah over what we say (is) a Guardian
Transliteration: qala lan ur'silahu ma'akum hatta tu'tuni mawthiqan mina al-lahi latatunnani bihi illa an yuhata bikum falamma atawhu mawthiqahum qala al-lahu ala ma naqulu wakilun
