Yusuf's Rank with the King of Egypt

Allah states that when he became aware of Yusuf's innocence and his innocense of what he was accused of, the king said,

ائْتُونِى بِهِ أَسْتَخْلِصْهُ لِنَفْسِى

Thereupon, Sayyidna Yusuf (علیہ السلام) said: اجْعَلْنِي عَلَىٰ خَزَائِنِ الْأَرْ‌ضِ ۖ إِنِّي حَفِيظٌ عَلِيمٌ that is, ` appoint me to the treasures of the land (which includes the produce of the land) for I am indeed a knowledgeable keeper (fully capable of conserving and guarding it, and aware of where to spend and how much to spend). (Qurtubi Mazhari)

In the two words appearing here (hafiz and alim), Sayyidna Yusuf (علیہ السلام) has combined together all functional virtues a genuine Finance Minister should have. To make it simple, it can be said that the chief trustee and manager of a national treasury needs to do two things: (1) He should not allow government property to be wasted, in fact, should collect, conserve and protect it fully. Then, he should see to it that it is not spent on non-deserving people, or on false heads of expenditure. (2) Then, he should not fall short in spending what has to be spent and where it has to be spent and, at the same time, he should not spend more than the quantum of the need. Thus, the word: حَفِیظ (hafiz : keeper) is the full guarantee of the first need, and the word: عَلِیم (` alim : knowledgeable), that of the second.
