10 Serious Consequences of Sins in Islam – Explained by Ibn al-Qayyim
Sins are not merely moments of weakness, they are spiritual wounds that leave lasting marks on the heart, soul, and even one’s life circumstances. Shaykh Ibn al-Qayyim (rahimahullah), one of the most profound scholars of the heart, detailed how sin affects a believer’s knowledge, provision, peace, and connection with Allah. His insights are timeless, serving as both a warning and a call to repentance.
Understanding the Reality of Sin
Every sin, big or small, leaves a trace. It clouds the heart, dims one’s spiritual vision, and makes worship more difficult. What starts as a single act of disobedience can grow into a habit that distances a person from Allah and weakens their will to return. As Ibn al-Qayyim explained, sins are not isolated events; they are causes with consequences that ripple through every part of life.
The Consequences of Sins According to Ibn al-Qayyim
1. Deprivation of Knowledge
Knowledge is a light from Allah, and sin extinguishes this light. Imam Malik once told Imam ash-Shafi’i, “I see that Allah has given light to your heart, do not extinguish it with the darkness of sin.” The more one sins, the harder it becomes to understand divine truths.
2. Loss of Provision (Rizq)
The Prophet ﷺ said: “A man is deprived of provision because of the sins he commits.” (Ibn Mājah 4022). Barakah (blessing) leaves one’s wealth, time, and health when sins are persistent.
3. Alienation from Allah and People
A sinner feels estranged, first from their Lord, then from those around them. One of the Salaf said, “When I disobey Allah, I see it in the attitude of my mount and my wife towards me.” Sin breeds discomfort, even in worldly relationships.
4. Hardship in Life
When a person fears Allah, Allah eases his affairs. But when sin dominates, every path becomes blocked. Small matters become heavy, and ease turns into burden, a sign that Allah’s aid has been withheld.
5. Darkness in the Heart
Obedience brings light; disobedience brings darkness. That inner darkness clouds judgment and may even show on one’s face. Ibn ‘Abbas said: “Good deeds bring radiance to the face, light to the heart, and love in people’s hearts for the believer. Sins bring darkness to the face, gloom to the heart, and hatred in people’s hearts for the sinner.”
6. Loss of Worship
If sin did nothing but prevent a person from worshipping Allah, it would be punishment enough. Each act of disobedience cuts off the road to another act of obedience, the sinner loses opportunities for khayr, like a man who eats food that makes him sick and is then deprived of what’s truly nourishing.
7. One Sin Leads to Another
Sins rarely occur in isolation. One leads to the next until a person becomes trapped in a cycle of disobedience, unable to break free. Repentance becomes harder the longer one delays.
8. Weakening of the Will to Repent
Continuous sin dulls the will to change. A person may still say “Astaghfirullah,” but the heart feels no remorse. Ibn al-Qayyim described this as one of the most dangerous states, outward repentance without inward sincerity.
9. Desensitisation to Sin
Eventually, sin becomes normal. The sinner feels no shame and may even boast of wrongdoing. The Prophet ﷺ warned: “All of my Ummah will be forgiven except those who publicise their sins.” (Al-Bukhārī 5721; Muslim 2990).
10. Sealing of the Heart
When sin becomes habitual, it leaves a stain on the heart, until it becomes rusted and sealed.
{كَلَّا بَلْ رَانَ عَلَىٰ قُلُوبِهِم مَّا كَانُوا يَكْسِبُونَ}
“Nay! But that which they used to do has covered their hearts.” (Surah al-Muṭaffifīn 83:14)
At this stage, guidance feels distant, and the person follows desire over truth.
A Call to Reflection and Repentance
Sins destroy the sweetness of īmān and rob a person of peace. Yet Allah’s mercy remains vast, no matter how dark the heart becomes, sincere repentance (tawbah) can bring it back to light. Ibn al-Qayyim reminds us that every sinner has a door open to Allah, as long as he has not turned away completely. Seek forgiveness before sin hardens into habit, and fill your days with remembrance, Qur’an, and gratitude.
Frequently Asked Questions (FAQs)
What does Islam say about the effects of sins?
Islam teaches that sins affect both the spiritual and worldly life of a believer, darkening the heart, reducing provision, and distancing a person from Allah’s mercy.
Can good deeds erase sins?
Yes. The Prophet ﷺ said: “Good deeds erase bad deeds.”
“Establish prayer at the two ends of the day and at the approach of the night. Indeed, good deeds erase bad deeds.” (Qur’an 11:114)
What’s the difference between a small and a major sin?
Major sins (kabā’ir) are those mentioned with specific punishments in the Qur’an or Sunnah, such as theft, murder, or riba. Minor sins can be forgiven through regular prayers and repentance, but persisting in them may make them major.
How can I protect my heart from the effects of sin?
Regular remembrance (dhikr), seeking forgiveness, and maintaining good company are key. Avoid environments that normalise sin, and stay connected to the Qur’an.
Does sin affect my rizq (provision)?
Yes, sin can affect your rizq (provision) and remove its barakah (blessing), not necessarily by taking away wealth itself, but by stripping its benefit and peace. While a specific hadith on this topic (Ibn Mājah 4022) is weak, the Qur’an clearly affirms that disobedience leads to deprivation, while obedience and taqwā bring abundance and ease.
“If only the people of the towns had believed and been mindful of Allah, We would have opened for them blessings from the heavens and the earth; but they denied (the truth), so We seized them for what they used to earn.”
Surah al-A‘rāf (7:96)
How does sin cause darkness in the heart?
Repeated disobedience covers the heart like smoke on glass, making it harder to reflect divine light. Only repentance and dhikr can polish it again.
Can a sinner still be loved by Allah?
Yes, if he repents sincerely. Allah loves those who constantly turn back to Him, no matter how many times they fall.
What if I keep committing the same sin?
Never despair. Keep repenting. Even if you fall a hundred times, each sincere repentance is accepted as long as your heart doesn’t insist on the sin.
What are signs that my heart is becoming hard?
When remembrance of Allah feels heavy, when sin feels easy, and when Qur’an no longer moves you, these are signs that the heart needs purification.
What’s the best du’a for repentance?
The Prophet ﷺ said: “Say: O Allah, You are my Lord, there is no god but You. You created me and I am Your servant... forgive me, for none forgives sins but You.” (Sahih al-Bukhari, 6306)
