[28].Surah Al-Qasas [The Narration]: Ayat 14

১৪. যখন মূসা যৌবনে পদার্পন করলেন এবং পরিনত বয়স্ক হয়ে গেলেন, তখন আমি তাঁকে প্রঞ্জা ও জ্ঞান দান করলাম। এমনিভাবে আমি সৎকর্মীদেরকে প্রতিদান দিয়ে থাকি।

Ayat 14. And when he attained his full strength, and was perfect (in manhood), We bestowed on him Hukman(Prophet hood, right judgment 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).

Tafseer of Surah Al-Qasas (The Narration) Ayat 14. When he reached full age, and was firmly established (in life), We bestowed on him wisdom and knowledge: for thus do We reward those who do good. Full age may be taken to be mature youth, say between 18 and 30 years of age. By that time a person is fully established in life: his physical build is completed, and his mental and moral habits are formed. In this case, as Moses was good at heart, true and loyal to his people, and obedient and just to those among whom he lived, he was granted wisdom and knowledge from on high, to be used for the times of conflict which were coming for him. His internal development being complete, he now goes out into the outer world, where he is again tried and proved, until he gets his divine commission.

Hazrat Abu Hurairah (May Allah be pleased with him) reported: The Messenger of Allah [SAWW](PBUH) said,  "Remember more often the destroyer of pleasures - death.''

[At-Tirmidhi Hadith # 2307].  

Lesson : as mentioned above in Surah Al-Qasas Ayat 14.“And thus do We reward the Muhsinun (i.e. good doers)”.Being heedful and talking about death checks man from being lost in the worldly pleasures and seductions. We are, therefore, supposed to remember death frequently and to avoid remaining indifferent to post-death affairs and occurrences.
