The Evil Effects of Sin

If we are not careful, we may become habitual in sins, especially minor sins. Ibn al-Qayyim (may Allah have mercy on him) described the effects of sins.

Sinning causes us to be deprived of knowledge for knowledge is light that Allah causes to reach the heart, and sin extinguishes that light. When Imam al-Shaafa’i sat before Imam Maalik and read to him, he admired him because of the intelligence, alertness and understanding that he saw in him. He said, “I think that Allah has caused light to enter your heart, so do not extinguish it with the darkness of sin.”

The second effect of sin is that it deprives a person of provision. The Messenger of Allah (SWAS) said: ‘A man is deprived of provision because of the sins that he commits.’”

Sins cause a sense of alienation between a person and his Lord, and between him and other people. One of the salaf said: “If I disobey Allah, I see that in the attitude of my riding beast and my wife.”

Things become difficult for a sinning person, so that he does not turn his attention towards any matter but he finds the way blocked or he finds it difficult. By the same token, for the one who fears Allah, things are made easy for him.

The sinner will find darkness in his heart, which he will feel just as he feels the darkness of night. So, this darkness affects his heart as the physical darkness affects his vision. For obedience is light and disobedience is darkness. The stronger the darkness grows, the greater becomes his confusion, until he falls into innovation, misguidance and other things that lead to doom, without even realizing, like a blind man who goes out in the darkness of the night, walking alone. This darkness grows stronger until it covers the eyes, then it grows stronger until it covers the face, which appears dark and is seen by everyone. ‘Abd-Allaah ibn ‘Abbaas said: “Good deeds make the face light, give light to the heart, and bring about ample provision, physical strength and love in people’s hearts. Bad deeds make the face dark, give darkness to the heart, and bring about physical weakness, a lack of provision and hatred in people’s hearts.”

Sin breeds sin until it dominates a person and he cannot escape from it.

Sin weakens a person’s willpower. It gradually strengthens his will to commit sin and weakens his will to repent until there is no will in his heart to repent at all… so he seeks forgiveness and expresses repentance, but it is merely words on the lips, like the repentance of the liars, whose hearts are still determined to commit sin and persist in it. This is one of the most serious diseases that are most likely to lead to doom.

A persistent sinner will become desensitized and will no longer find sin abhorrent, so it will become his habit, and he will not be bothered if people see him committing the sin or talk about him.

The Prophet (SWAS) said: “All of my ummah will be fine except for those who commit sin openly, and that includes cases where Allah conceals a person’s sin, but the following morning he exposes himself and says, ‘O So and so, I did such and such last night, so he shamelessly exposes himself when all night his Lord had concealed his sin.”

When there are many sins they leave a mark on the heart of the person who commits them, so he becomes one of the negligent. As one of the salaf said, concerning the aayah (verse)–

كَلَّا بَلْ رَانَ عَلَىٰ قُلُوبِهِم مَّا كَانُوا يَكْسِبُونَ

“Nay! But on their hearts is the Raan which they used to earn” [83:14] 

this means sin after sin.

How this starts is that the heart gets stained by sin, and if the sin increases then the stain grows bigger until it becomes the raan, then it increases until it becomes a seal, and the heart becomes covered and sealed. If that happens after a person had been guided and had understood, then his heart is turned upside down, and at that point the Shaytaan gains control over him and directs him as he wants.
