﴿ وَلَمَّا دَخَلُوا۟ مِنْ حَيْثُ أَمَرَهُمْ أَبُوهُم مَّا كَانَ يُغْنِى عَنْهُم مِّنَ ٱللَّهِ مِن شَىْءٍ إِلَّا حَاجَةًۭ فِى نَفْسِ يَعْقُوبَ قَضَىٰهَا ۚ وَإِنَّهُۥ لَذُو عِلْمٍۢ لِّمَا عَلَّمْنَٰهُ وَلَٰكِنَّ أَكْثَرَ ٱلنَّاسِ لَا يَعْلَمُونَ ﴾

“But although they entered [Joseph's city] in the way their father had bidden them, this proved of no avail whatever to them against [the plan of] God [His request] had served only to satisfy Jacob's heartfelt desire [to protect them]: for, behold, thanks to what We had imparted unto him, he was indeed endowed with the knowledge [that God's will must always prevail]; but most people know it not.”

God exalted be He says And when they entered in the manner which their father had bidden them that is separately it did not avail them anything min shay’in min is extra against God that is against His decree; it was but a need in Jacob’s soul which he thus satisfied and this need was his desire to fend off the evil eye from them out of affection for them. And verily he was possessed of knowledge because We had taught him; but most of mankind — and they are the disbelievers — do not know about God’s inspiring His elect.
