Categories of Sins and Areas of Uncertainty
When delving into the depths of Islamic ethics, understanding the different dimensions of sin is crucial. The works of Imam Ghazali offer significant guidance in this regard; he divides sins into three main categories: major, minor, and doubtful. However, he emphasizes that this classification is not absolute. It is often impossible to make a clear distinction as to whether each sin is definitively major or minor, as this depends on individual intentions, context, and many other variable factors. Therefore, attempting to limit the categories of sins with precise numbers is an unattainable goal, because such details have not been transmitted from our Prophet (peace be upon him); rather, general principles and guidelines are provided. This means that just as the Night of Power blends into other nights, so too some sins may have unclear boundaries.
The Foundation of Spirituality: Knowing God and Being a Servant
According to Ghazali, the primary purpose of moral actions is to lead people to Allah’s pleasure. The way to achieve this goal lies first in knowing Allah’s essence, attributes, Book, and Messengers. A person cannot be a servant without knowing their Lord; and being a servant is possible only through adhering to the fundamental principles of Sharia. The very purpose of sending prophets is to make people servants of Allah. Therefore, worldly life is a means to the afterlife journey, and acquiring spiritual knowledge is essential in this journey. Since the continuity of life is a prerequisite for reaching the Hereafter, protecting the world is also important; because life, wealth, and knowledge are the three fundamental elements of existence. Anything that hinders knowing Allah is considered a major sin, and this can lead to the closing of the doors of life and livelihood.
Levels of Major Sins: Faith, Life, and Sustenance
Ghazali builds major sins upon three levels. The first level includes those that hinder knowing Allah and His Messenger; these are considered disbelief and are among the most serious of sins. The second level involves actions that disrupt the continuity of life: such as murder or self-harm. Because such acts eliminate life, which is a fundamental element for reaching the afterlife journey. The third level relates to sustenance and livelihood: acquiring wealth through unjust means or violating the rights of others. Mistakes can be made in all three levels, but their weight and consequences are different. While it may be possible to correct the mistake of one who acquires wealth unjustly, this opportunity may not exist for others.
