The human soul is very complicated. And its creation is a miracle. It is very light, it can change from one state to the other lightly and quickly. The soul is affected by the surrounding environment. It includes love, hate, will, apprehension, arrogance, self-conceit and rancour. It can have soul diseases. And it can be purifies.
Allah says in Surat Ashams: “And [by] the soul and He who proportioned it, And inspired it [with discernment of] its wickedness and its righteousness, He has succeeded who purifies it, And he has failed who instills it [with corruption]” [Ash-Shams 7-10]
What is the human Soul?
To understand the human soul, we will track the description of the soul in the Quran:
“And I do not acquit myself. Indeed, the soul is a persistent enjoiner of evil, except those upon which my Lord has mercy. Indeed, my Lord is Forgiving and Merciful.” [Yusuf 53]
“And if We give man a taste of mercy from Us and then We withdraw it from him. Indeed, he is despairing and ungrateful.”[ Hud 9]
“And He gave you from all you asked of Him, And if you should count the favor of Allah , you could not enumerate them. Indeed, mankind is [generally] most unjust and ungrateful.” [Ibrahim 34]
“And man supplicates for evil as he supplicates for good, and man is ever hasty.” [Al Isra 11]
“And when adversity touches you at sea, lost are [all] those you invoke except for Him. But when He delivers you to the land, you turn away [from Him]. And ever is man ungrateful.” [Al Isra 67]
“And when We bestow favor upon the disbeliever, he turns away and distances himself, and when evil touches him, he is ever despairing.” [Al Isra 83]
“Say [to them], “If you possessed the depositories of the mercy of my Lord, then you would withhold out of fear of spending.” And ever has man been stingy.” [Al Isra 100]
“And We have certainly diversified in this Qur’an for the people from every [kind of] example; but man has ever been, most of anything, [prone to] dispute.” [Al Kahf 54]
“Verily, man (disbeliever) was created very impatient;’ [Al ma’arij 19]
As you can see, all the description of the human in the Quran is bad, so if we followed our souls we will go astray, Allah says in Surat Yusuf “the soul is a persistent enjoiner of evil” [Yusuf 53]. You discover that in Ramadan, when you find yourself doing haram things, and then you know that these things come from your soul not from Shaitan.
Allah mentioned the description of the soul in the Quran in order for us to know what will happen when we follow our souls.
What if we followed our souls?
If the soul is left un-tamed, the human will disobey Allah and eventually this soul will die, this person will not be aware of Allah’s awareness, will not fear Allah, will not feel remorse and so will not repent.
The one who will succeed, who will enter paradise, is the one who purifies his soul from all these bad manners. “The Day when there will not benefit [anyone] wealth or children But only one who comes to Allah with a sound heart.”[As Shu’ara’ 88-89].the only thing that will benefit anyone on the Day of Judgment is his sound heart. Purifying your heart comes with obeying Allah. When you obey Allah, your soul will grow and so, you will get rid of all these bad manners.
Also purifying your soul, makes you live peacefully and happil. As the reasons of most of the problems that people have is due to heart diseases.
All people has thoughts about some soul diseases. But your reaction towards this thought is what you will be judged for. For example, you may see someone who is richer than you, and for a moment you have a thought of envy. But your reaction towards this thought is what you will be judged for, whether you envied him or you didn’t.
How to know that you have soul diseases?
Soul diseases are not connected to the appearing worships as it lays in the heart. If someone prays all the prayer on time and pray all the nafl, always remembering Allah with his tongue only. His looks is according to the sunnah, but his heart is not aware of Allah or he has self-conceit because he does all of that, or he thinks he is better than others then this person has a heart disease.
If your heart is full of arrogance, hatred, self-conceit or rancour, then you have a disease in your soul. Soul diseases include hypocrisy, riyaa, doubt, suspicion, mistrust, jealousy, envy, arrogance, self-conceit, hatred, rancour, despair, loving others than Allah, fearing others than Allah, obsession, hardening of the heart and following the falsehood.
Every person should search for soul diseases in his heart occasionally. As it creeps secretly like the creeps of an ant. Search for it and once you find it treat it.
