[27].Surah Al-Naml [The Ants]: Ayat 4-6

৪. যারা পরকালে বিশ্বাস করে না, আমি তাদের দৃষ্টিতে তাদের কর্মকান্ডকে সুশোভিত করে দিয়েছি। অতএব, তারা উদভ্রান্ত হয়ে ঘুরে বেড়ায়। 
৫. তাদের জন্যেই রয়েছে মন্দ শাস্তি এবং তারাই পরকালে অধিক ক্ষতিগ্রস্ত।
৬. এবং আপনাকে কোরআন প্রদত্ত হচ্ছে প্রজ্ঞাময়, জ্ঞানময় আল্লাহর কাছ থেকে। 

Ayat 4. Verily, those who believe not in the Hereafter, We have made their deeds fair-seeming to them, so they wander about blindly.

Ayat 5. They are those for whom there will be an evil torment (in this world). And in the Hereafter they will be the greatest losers.

Ayat 6. And verily, you (O Muhammad  SAWW(PBUH) are receiving the Qur'an from the One, All-Wise, All-Knowing." 

Tafseer of Surah Al Naml (The Ants) Ayat 04 to 06. As to those who believe not in the Hereafter, We have made their deeds pleasing in their eyes; and so they wander about in distraction. Those who reject Allah and follow Evil have a good conceit of themselves. Their deeds are pleasing to no one else. As they have rejected Allah's guidance, they are allowed to embrace their own self-conceit, and given further respite for repentance. But they follow their own whims and wander about in distraction, as they have no standards such as guide the godly. Such are they for whom a grievous Penalty is (waiting); and in the Hereafter theirs will be the greatest loss. The account will then be made up, and they will be found to be terribly in loss. They will be the worst in loss, for all their self-complacency. As to thee, the Qur´an is bestowed upon thee from the presence of one who is wise and all-knowing.

Hazrat Anas (May Allah be pleased with him) said: You indulge in (bad) actions which are more insignificant to you than a hair while we considered them at the time of Messenger of Allah [SAWW](PBUH) to be great destroying sins".

[Al-Bukhari 08, Chapter 76, Hadith # 499]. 

Lesson : as mentioned above in Surah Al-Naml Ayat 04."Verily, those who believe not in the Hereafter, We have made their deeds fair-seeming to them, so they wander about blindly" The less fear of Allah, one has the more disobedient he becomes to Him. As the fear of Allah decreases, one becomes more bold in committing sins. As the Companions of the Prophet [SAWW](PBUH) were intensely fearful of Allah, they were afraid of committing even very minor sins.
