سورة Al-Qasas ( The Stories ) - الآية 14

And when he attained his full strength, and was perfect (in manhood), We bestowed on him Hukman (Prophethood, right judgement of the affairs) and religious knowledge [of the religion of his forefathers i.e. Islamic Monotheism]. And thus do We reward the Muhsinun (i.e. good doers - see the footnote of V. 9:120).
