Aug 26, 2025
In Islamic theology, sin (ithm) represents any act of disobedience to Allah’s commands, whether through commission or omission. The concept of sin is fundamental to understanding human nature, spiritual development, and the path to salvation in Islam. This comprehensive guide explores the major sins (Kaba’ir) in Islam, their classification, consequences, and the mercy of Allah through repentance.
The Quran narrates how Satan (Iblis) became humanity’s eternal enemy after refusing to prostrate before Adam (peace be upon him). When expelled from Allah’s presence, Satan requested respite to mislead mankind until the Day of Judgment. Allah granted this request, and Satan declared his challenge:
فَبِعِزَّتِكَ لَأُغْوِيَنَّهُمْ أَجْمَعِينَ إِلَّا عِبَادَكَ مِنْهُمُ الْمُخْلَصِينَ
“By Your might, I will surely mislead them all, except Your chosen servants among them.” (Quran 38:82-83)
Satan employs a systematic approach to lead humans astray, as described in the Quran:
لَأَقْعُدَنَّ لَهُمْ صِرَاطَكَ الْمُسْتَقِيمَ ثُمَّ لَآتِيَنَّهُمْ مِنْ بَيْنِ أَيْدِيهِمْ وَمِنْ خَلْفِهِمْ وَعَنْ أَيْمَانِهِمْ وَعَنْ شَمَائِلِهِمْ وَلَا تَجِدُ أَكْثَرَهُمْ شَاكِرِينَ
“I will surely sit in wait for them on Your straight path. Then I will come to them from before them and from behind them and on their right and on their left, and You will not find most of them grateful to You.” (Quran 7:16-17)
Satan’s strategy involves:
The most comprehensive definition of sin comes from Prophet Muhammad (peace be upon him):
Arabic Text:
وَالْإِثْمُ مَا حَاكَ فِي صَدْرِكَ، وَكَرِهْتَ أَنْ يَطَّلِعَ عَلَيْهِ النَّاسُ
“Sin is what troubles your conscience and what you would dislike people to know about.”
(Sahih Muslim: 6195)
This definition emphasizes the internal moral compass that Allah has placed within every human being.
Major sins are defined as transgressions that:
Minor sins are lesser transgressions that do not carry the severe consequences of major sins. These include:
Important Note: Persistent minor sins can accumulate to become major sins if not addressed through repentance.
Definition: Shirk is the gravest sin in Islam, involving the worship of anyone or anything besides Allah or alongside Allah.
Quranic Evidence:
إِنَّ اللَّهَ لَا يَغْفِرُ أَنْ يُشْرَكَ بِهِ وَيَغْفِرُ مَا دُونَ ذَٰلِكَ لِمَنْ يَشَاءُ ۚ وَمَنْ يُشْرِكْ بِاللَّهِ فَقَدِ افْتَرَىٰ إِثْمًا عَظِيمًا
“Indeed, Allah does not forgive that partners be associated with Him, but forgives what is less than that for whom He wills. And whoever associates partners with Allah has certainly fabricated a tremendous sin.” (Quran 4:48)

رَبَّنَا لَا تُؤَاخِذْنَا إِنْ نَسِينَا أَوْ أَخْطَأْنَا ۚ رَبَّنَا وَلَا تَحْمِلْ عَلَيْنَا إِصْرًا كَمَا حَمَلْتَهُ عَلَى الَّذِينَ مِنْ قَبْلِنَا ۚ رَبَّنَا وَلَا تُحَمِّلْنَا مَا لَا طَاقَةَ لَنَا بِهِ ۖ وَاعْفُ عَنَّا وَاغْفِرْ لَنَا وَارْحَمْنَا
“Our Lord, do not impose blame upon us if we have forgotten or erred. Our Lord, and lay not upon us a burden like that which You laid upon those before us. Our Lord, and burden us not with that which we have no ability to bear. And pardon us; and forgive us; and have mercy upon us.” (Quran 2:286)
May Allah protect us all from major sins and guide us to the straight path. Ameen.
