[23].Surah Al-Muminun [The Believers]: Ayat 45-48

৪৫) তারপর আমি মূসা ও তার ভাই হারুনকে নিজের নিদর্শনাবলী ও সুস্পষ্ট প্রমাণ  সহকারে ফেরাউন ও তার রাজ পারিষদদের কাছে পাঠালাম ৷
৪৬) কিন্তু তারা অহংকার করলো এবং তারা ছিল বড়ই আস্ফালনকারী৷ 
৪৭) তারা বলতে লাগলো, ‘‘আমরা কি আমাদেরই মতো দু’জন লোকের প্রতি ঈমান আনবো?  আর তারা আবার এমন লোক যাদের সম্প্রদায় আমাদের দাস ৷’’ 
৪৮) কাজেই তারা উভয়কে প্রত্যাখ্যান করলো এবং ধ্বংসপ্রাপ্তদের মধ্যে শামিল হলো৷

Ayat 45. Then Allah sent Musa PBUH(Moses) and his brother Harun PBUH(Aaron), with Allah's Ayat (proofs, evidences, verses, lessons, signs, revelations, etc.) and manifest authority,

Ayat 46. To Firaun (Pharaoh) and his chiefs, but they behaved insolently and they were people self-exalting (by disobeying their Lord, and exalting themselves over and above the Messenger of Allah).

Ayat 47. They said: "Shall we believe in two men like ourselves, and their people are obedient to us with humility (and we use them to serve us as we like)."

Ayat 48. So they denied them both [Musa PBUH(Moses) and Harun PBUH(Aaron)] and became of those who were destroyed. 

[Tafseer] of ayat 45. Then Allah sent Moses and his brother Aaron, Signs and authority manifest, they had a twofold mission: (1) to Pharaoh and his Court, which failed because of Egyptian arrogance; (2) to the Israelites, for whom the Law was received on Mount Sinai , but they repeatedly rebelled against Allah. In both cases there were miracles ("Clear Signs") and other proofs which showed that they came at Allah's command and were inspired by His authority. in ayat 46. Pharaoh and his Chiefs: behaved insolently: they were clerly arrogant people and in response they said to Prophets PBHU : "Shall we believe in in you two men like ourselves? And their people are subject to us!" Racial arrogance made the Egyptians say, 'These men belong to a race which we hold in subjection as our slaves: how can we accept them as messengers of Allah?' they accused them of falsehood, and they became of those who were destroyed. 

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-Muminun Ayat 48."they denied them both and became of those who were destroyed" 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.
