How Musa killed a Coptic Man

Having described Musa's beginnings, Allah then tells us that when he reached maturity, and was complete in stature, Allah gave him Hukm and religious knowledge. Mujahid said that this means prophethood.

وَكَذَلِكَ نَجْزِى الْمُحْسِنِينَ

Commentary

وَلَمَّا بَلَغَ أَشُدَّهُ وَاسْتَوَىٰ (And when he reached his maturity and became perfect - 28:14). The literal meaning of 'ashudd (أَشُدَّ ) is to attain the peak of strength or intensity. For instance a person gradually develops from the position of juvenile weakness to the strength of adulthood. A time comes when he has attained full strength and vigour that he could achieve. That point in life is called أَشُدَّ 'ashudd. In different parts of the world and for different people this point in life varies according to climate, character of the land, race etc. Some people attain it early while others take time. ` Abd Ibn Humaid has reported that Sayyidna Ibn ` Abbas and Mujahid have placed the age of 'ashudd as 33rd year of one's life. This is called the age of perfection or the age of discernment, when the development of body stops after reaching its peak. After this age a period of hold commences, which lasts until the age of forty. This period is mentioned in the verse as اسْتَوَىٰ Istawa (translated above as became perfect). After the age of forty years the decline and weakness sets in. Hence, it can be said that 'ashudd (أَشُدَّ ) of a person starts from the age of 33 years and lasts through 40 years. (Ruh, Qurtubi).
