Almuntakhab Fi Tafsir Alquran Alkarim

Then when he –Yusuf- reached the stage of life wherein he had the ability for effective action and firmness of mind, character, will and purpose, We imparted to him wisdom and divine knowledge. For thus do We reward those who perfect their illustrious toils and turn their thoughts on moral excellence and benevolence

Tafseer Tafheem-ul-Quran by Syed Abu-al-A'la Maududi

(12:22) And when he reached his full maturity, We bestowed on him judgement and knowledge. *20 This is how We reward the righteous people.

And when Joseph reached maturity, We gave him judgment and knowledge. And meaning

*20) By the use of such words as the Qur'an usually means, "We bestowed on him Prophethood," for the Arabic word (hukmun) stands for both judgement and "authority" and (`ilmun) hen stands for that Knowledge which is directly revealed to the Prophets by Allah. Thus, the Arabic words of the Text will mean: "We gave him the power and the authority and the knowledge needed for judging rightly the affairs of the people."
