ولما دخلوا من حيث أمرهم أبوهم ما كان يغني عنهم من الله (12:68) بالانجليزي

(12:68) However know it well that I cannot ward off from you Allah's will for none other than He has any authority whatsoever. In Him I have put my trust and all who want to rely upon anyone should put their trust in Him alone. " And it so happened that when they entered the city by different gates as their father had advised them the precautionary measure proved ineffective against Allah's will. Of course Jacob had done his best to avert the fear he had in his heart. Indeed he possessed knowledge because of what We had taught him: but most people do not understand the reality of the matter. *54

*54) "Most people do not understand. . . . " how Prophet Jacob was able to hold the balance between "trust in Allah" and adoption of precautionary measures. This was because Allah had favoured him with the real knowledge. That was why he took all those measures which were dictated by common sense, deep thinking and experience. He admonished them for their ill treatment with their brother Joseph so that they should not dare repeat it in the case of Benjamin. He took a solemn pledge from them in the name of AIlah that they would take good care of the safety of their step-brother. Then he advised them to be on their guard against the dangerous political situation and to enter the capital by different gates so as not to give cause for alarm and suspicion. In short, as far as it was humanly possible, he took all the precautionary measures to avoid every possible risk. On the other hand, he always kept this thing in view (and expressed it) that no human precautionary measure could avert the enforcement of Allah's will, and that the real protection was Allah's protection: and that one should not rely on the precautionary measures but on the favour of AIlah. Obviously only that person who has the real knowledge can keep such a balance in his words and deeds, who knows what kind of efforts are demanded of his human faculties bestowed by Allah for the solution of worldly problems, who also realizes that it is Allah alone Who has the power to make them a success or a failure. This is "what most people do not understand" . Some of them rely merely on their efforts and measures and discard trust in Allah; while there are others who rely merely on "trust in AIlah" and do not adopt any practical measure to solve their problem.
