22 Preface وَلَمّا بَلَغَ أَشُدَّهُ آتَيناهُ حُكمًا وَعِلمًا ۚ وَكَذٰلِكَ نَجزِي المُحسِنينَYusuf AliWhen Joseph attained1 His full manhood, We gave him power and knowledge: thus do We reward those who do right.2When Joseph left Canaan, he was a young and immature lad of seventeen or eighteen, but his nature was innocent and good. Through the vicissitudes of his fortune in Egypt, he grew in knowledge, judgment, and power.Muhsinin: those who do right, those who do good. Both ideas are implied. In following the right conduct, you are necessarily doing good to yourself and to others.
