From among the punishments of sins is that they can lead to a decrease in the intellect of the sinner. You will not find two intellects, one obedient to Allaah and the other disobedient, except that the obedient mind is more plentiful and more complete. Its thinking is sounder and its opinion is often more correct.
Allaah has stated,
فَاتَّقُوا اللَّـهَ يَا أُولِي الْأَلْبَابِ لَعَلَّكُمْ تُفْلِحُونَ ﴿١٠٠
“So fear Allaah, O men of understanding, so that perhaps you may be successful.” [Sooratul Ma’idaah (5):100]
And, He has said,
وَمَا يَذَّكَّرُ إِلَّا أُولُو الْأَلْبَابِ ﴿٢٦٩
“And none are reminded except men of understanding.” [Sooraatul Baqaraah (2):269]
In light of this, how is it that the intellect of the sinner who disobeys the One Who has his soul in His possession, is endowed with reason and understanding? This servant knows that Allaah sees him and is a witness to his every movement.still, the transgressor disobeys Allaah in His presence, not hidden from His view! This one seeks his Lord’s help through (begging Him for) His blessings and (protection) against His wrath, but due to sins he invokes His Lord’s wrath and curse upon himself.
With every act of disobedience, the sinner distances himself from the nearness to Allaah and (draws closer) to the explusion from Allaah’s domain. The sinner continues to invoke His Lord’s abandonment of him. Consequently, the unrighteous is left alone with his enemy, (Shaytaan). The disobedient servant falls out of favor with his Creator and his deprived of His pleasure and love.The victory of being close to Allaah and gazing upon His Merciful Grace alongside the other righteous servants, escapes him.
Thus, what is the reasoning of a person who prefers the enjoyment of an hour, a day,or (even) a lifetime that when it ceases to exist, it will appear as though it were a dream, over a permanent happiness and great achievement? Were it not for his ability to reason, a sinful servant such as this would be considered insane. Sometimes, being mad or insane will be a better situation with a safer outcome (than that of the sinner).
However, the effects of the sin upon the lifestyle of the individual suffering from a damaged mind, is not always evident. In addition, there are various kinds of insanity. “O how wonderful it is that if the understanding is sound, it is mindful of the way to achieve success, enjoyment, happiness and a good life through contentment with all the blessings (found) within seeking the pleasure of Allaah. And, it knows that suffering and punishment lies within invoking the anger of Allaah.”
The mind dutiful servant to Allaah is aware of the truth that the delight of the eye (seeing the Merciful Face of Allaah), happiness, of the souls,enlightenment of the hearts and living the eternal good life, are all contained in seeking the pleasure of Allaah. These are the rewards that are unequalled by any of the temporary pleasures in this life. Moreover, whenever the hearts of the righteous contemplate this promise of Allaah, it grows discontented with this life and its trivial amusements as a substitute.
Nonetheless, this fortunate individual values his share of this world as something more significant than pomp and glitter. He does not spoil his enjoyment by craving its trivial portion. Those who seek the mere show of this life, their enjoyment are corrupted. The ecstasy that comes with obtaining something of this life turns into sorrow and anxiety. On the other hand, the obedient servant will experience his enjoyment twice – the pleasure that accompanies the acquirement of something from this Dunya. However, he patiently waits for the ultimate good (the Paradise) believing that it is unimaginably better than any pleasure he can experience or any pain he may endure in this world.
The matter is like the statement of Allaah,
إِن تَكُونُوا تَأْلَمُونَ فَإِنَّهُمْ يَأْلَمُونَ كَمَا تَأْلَمُونَ ۖ وَتَرْجُونَ مِنَ اللَّـهِ مَا لَا يَرْجُونَ ۗ وَكَانَ اللَّـهُ
عَلِيمًا حَكِيمًا ﴿١٠٤
“If you are suffering (hardships) then surely they (too) are suffering (hardships) as you are suffering, but you have a hope from Allaah (for the reward i.e. Paradise) that for which they hope not.” [Sooratun-Nisaa (4):104]
There is no deity worthy of worship except Allaah.
How deficient is the intellect of the one who sells pearls for dung or musk for excrement? He trades the companionship of those whom Allaah has bestowed His favor upon from amongst the Prophets, the truthful, the martyrs and the righteous, for the companions of those who Allaah’s anger and wrath are upon.And, he has prepared for them the Hell-fire, an evil abode.
