[23].Surah Al-Muminun [The Believers]:Ayat 71

৭১) আর সত্য যদি কখনো তাদের প্রবৃত্তির অনুসরণ করতো তাহলে আকাশ ও পৃথিবী এবং তাদের মধ্যের সবকিছুর ব্যবস্থাপনা ওলট পালট হয়ে যেতো।  না, বরং আমি তাদের নিজেদের কথাই তাদের কাছে এনেছি এবং তারা নিজেদের কথা থেকে মুখ ফিরিয়ে নিচ্ছে৷

Ayat 71. And if the truth had been in accordance with their desires, verily, the heavens and the earth, and whosoever is therein would have been corrupted! Nay, We have brought them their reminder, but they turn away from their reminder.  

[Tafseer] of Ayat 71. If the Truth had been in accord with their desires, truly the heavens and the earth, and all beings therein would have been in confusion and corruption! Nay, We have sent them their admonition, but they turn away from their admonition. Allah is All-Wise and All-Good, and His architecture of the universe is on a perfect Plan. If these poor, low, selfish, ignorant creatures were to plan it according to their hearts' desires, it would be a dreadful world, full of confusion and corruption. 

Hazrat Abdullah bin Masud (May Allah be pleased with him) reported: Messenger of Allah [SAWW](PBUH) said, "Never a Prophet had been sent before me by Allah to his people but he had, among his people, (his) disciples and companions, who followed his ways and obeyed his command. Then there came after them their successors who proclaimed what they did not practise, and practised what they were not commanded to do. And (he) who strove against them with his hand is a believer; he who strove against them with his heart is a believer; and he who strove against them with his tongue is a believer ; and beyond that there is no grain of Faith".

[Muslim Book 01, Chapter 21, Hadith # 081] 

Lesson : as mentioned above in Surah Al-Muminun Ayat 71."if the truth had been in accordance with their desires" This Hadith contains a very important prescription to prevent the Muslim society from all things which are forbidden in Islam. So long as Muslims adhered to it and ceaselessly and fearlessly performed their obligation of enjoining the right and forbidding the wrong, their society was largely safe from many evils and sins.
