They find Their Money returned to Their Bags

Allah says, when Yusuf's brothers opened their bags, they found their merchandise inside them, for Yusuf had ordered his servants to return it to their bags. When they found their merchandise in their bags,

قَالُواْ يأَبَانَا مَا نَبْغِى

After hearing what they said, their father answered: لَنْ أُرْ‌سِلَهُ مَعَكُمْ حَتَّىٰ تُؤْتُونِ مَوْثِقًا مِّنَ اللَّـهِ لَتَأْتُنَّنِي بِهِ (I shall never send Benyamin with you until you give me a pledge in the name of Allah that you will definitely bring him back to me - 66). But, could someone with the ability to see reality ever miss to realize that man, no matter how strong he may be, is, after all, dependent and helpless before the all-pervading power of Allah jalla thana'uhu - how then, and on what basis, would he give a pledge to bring back someone safe? The reason is that he does not have the absolute power and control to accomplish it. Therefore, when Sayyidna Ya` qub علیہ السلام asked his sons to give him a pledge, he added an exception to it by saying: إِلَّا أَن يُحَاطَ بِكُمْ ` unless you are overpowered (by circumstances).' Early Tafsir authority, Mujahid explains it as: unless all of you are killed. Another early Tafsir authority, Qatadah says that it means: unless you become totally helpless and overpowered.

In the last sentence of verse 66, it was said: فَلَمَّا آتَوْهُ مَوْثِقَهُمْ قَالَ اللَّـهُ عَلَىٰ مَا نَقُولُ وَكِيلٌ (So, when they gave him their pledge, he said, "Allah is watchful over what we say" ), that is, when his sons gave the pledge as desired on solemn oaths to satisfy their father, then, Sayyidna Ya` qub (علیہ السلام) told them that the giving and taking of solemn oaths being undertaken by them is something which ultimately rests with Allah Ta ala alone. It is with His taufiq only that one person can keep the other protected and thus become enabled to fulfill his pledge. Otherwise, man is helpless. He has nothing under his personal control.
