Sin is an objective act of disobedience against divine commands, while shame is an emotion; it can be 'Hayaa'' (modesty that prevents sin) or 'remorse' (guilt after sin that leads to repentance).
To differentiate between sin and shame, we must delve deeper into the definitions and natures of each from the perspective of Quranic and Islamic teachings. Sin, at its core, is an act of disobedience and transgression against the divine commands and boundaries set by Allah Almighty in the Holy Quran and through His prophets. Sin is an objective and specific concept; whether this sin is manifest (like theft, murder, adultery) or hidden (like envy, arrogance, backbiting). The Holy Quran clearly refers to actions that are considered sins and has established worldly and otherworldly consequences for them. These actions cross the boundaries set by God and are considered an infringement upon the rights of Allah or the rights of people (Huquq al-Allah or Huquq al-Nas). For instance, numerous verses prohibit polytheism, usury, oppression, lying, and obscenity, all of which are considered sins. Allah in the Quran has always kept the door of repentance and return from sin open, emphasizing His forgiveness and mercy, provided that a person returns to Him with true remorse and a resolve not to repeat the sin. This indicates that sin is a voluntary act, capable of being atoned for through repentance, and its nature lies outside the individual's will and emotion; that is, regardless of whether a person feels shame or not, an act that is contrary to divine command is a sin. In contrast, 'shame' is an emotion and a state of feeling. This emotion can have two distinct and important facets, which are crucial to differentiate: one is 'Hayaa'' (Modesty/Bashfulness), which is a moral virtue and a commendable state, and the other is 'Nadam' or 'Azaab al-Wijdan' (Remorse/Guilt) that arises after committing a wrong act. Hayaa' is an inner force that prevents a person from committing indecent and unlawful acts. This type of shame is preventive and acts as a factor in preserving chastity, purity, and respecting the rights of others. The Prophet Muhammad (peace be upon him) said: "Hayaa' is a branch of faith." This hadith shows that Hayaa' is a faithful and valuable characteristic that guides an individual towards goodness and prevents them from committing sins. A person who possesses Hayaa' refrains from doing things that are not befitting of a believing person due to their inner feeling, and even before committing an act, they feel a sense of shame that prevents them from it. This Hayaa' is also indirectly affirmed in the Quran through recommendations for modesty and appropriate dress and control of gaze (such as verses in Surah An-Nur). Hayaa' is a moral defense mechanism that preserves a person's spiritual boundaries and prevents them from entering the realm of sin. However, the second aspect of shame, namely remorse and guilt, is a feeling that arises *after* committing a sin. This type of shame is a sign of a living conscience and an awakening heart. When a person commits a sin and subsequently feels regret, embarrassment, and guilt, this feeling can lead them towards repentance and seeking forgiveness. In essence, this shame is an opportunity to return to the right path and rectify mistakes. The Holy Quran repeatedly emphasizes the importance of repentance and turning back to Allah, and this inner remorse is the first step on the path of repentance. For example, the story of Adam and Eve in the Quran (Surah Al-A'raf, verse 23) demonstrates this very remorse after an error and their plea for forgiveness from Allah, which led to their repentance and return. Therefore, the key difference is that sin is an *action* or *omission* forbidden by Allah, whereas shame is an *emotion*. Sin is objective, and shame is subjective. A person might commit a sin and feel no shame from it (like those whose hearts have hardened), and this does not mean that the act is not a sin. Conversely, a person might feel ashamed of something that is not religiously considered a sin, such as shame over poverty or a physical defect, which fundamentally has no relation to divine disobedience. Islam considers sin a spiritual ailment that requires healing (repentance), while it considers Hayaa' a virtue and remorse a warning signal and a reminder to return to one's pure nature. Understanding this distinction is vital because it helps us accept responsibility for our actions (sin) and, at the same time, preserve our spiritual and moral health through the virtue of Hayaa' and, through remorse after sin, embark on the path of repentance and rectification. This differentiation empowers us to weigh our actions by divine standards and align our emotions with divine guidance to achieve prosperity in this world and the hereafter.
Say, 'O My servants who have transgressed against themselves [by committing sins], do not despair of the mercy of Allah. Indeed, Allah forgives all sins. Indeed, it is He who is the Forgiving, the Merciful.'
Then one of the two women came to him walking shyly. She said, 'Indeed, my father invites you that he may reward you for having watered for us.' So when he came to him and recounted to him the story, he said, 'Fear not. You have escaped from the wrongdoing people.'
O you who have believed, avoid much [negative] assumption. Indeed, some assumption is sin. And do not spy or backbite each other. Would one of you like to eat the flesh of his brother when dead? You would detest it. And fear Allah; indeed, Allah is Accepting of repentance and Merciful.
One day, a wealthy man approached the master of eloquence, Saadi, and asked with a distressed look: "O wise one, I have committed a hidden sin that no one but God knows about. Yet, a shame has fallen upon my heart, robbing me of peace. Is this shame the sin itself?" Saadi smiled and said: "My friend, sin is like a thorn that has pierced someone's foot, and that thorn is within your foot; it is an action inconsistent with divine command, and you have committed it. But your shame is like the pain you feel after the thorn has pierced, a pain that calls you to pull out the thorn and heal the wound. If you had ignored that thorn and felt no pain, then you should have been worried, for there would be no sign of your heart's health left. This shame is an inner call inviting you towards repentance and purity. Do not fear this shame, but rather repent from that sin and make this feeling a ladder for your ascent." The wealthy man found peace upon hearing these words and decided to repent from his sin and adorn his heart with purity and modesty.
