89 | How to Ruin Your Afterlife

Backbiting is defined by the Prophet Muhammad ﷺ as mentioning about another person that which they would dislike, even if it is true. If the statement is false, it becomes slander, which is an even more heinous crime. The moral gravity of this sin is not symbolic rhetoric; it is a description of an unseen reality. The Prophet ﷺ narrated the incident of two women who fasted outwardly while engaging in backbiting. When instructed to vomit, they expelled blood and pieces of rotten flesh, and he explained that they had broken their fast upon what God had made unlawful. The lesson is profound: outward acts of worship do not compensate for corruption of character.

These two women fasted from what Allah made lawful for them, but they broke their fast on what Allah made unlawful. They sat backbiting people, and this is the flesh of the people they were eating.

Prophet Muhammad ﷺ, (Musnad Ahmad)

The Qur’an explicitly condemns backbiting in Surah al-Ḥujurāt (49:12), warning believers to avoid suspicion, spying, and speaking ill of one another. The vivid imagery of cannibalism is meant to awaken the conscience and instill moral revulsion toward such behavior. Islam places immense emphasis on guarding the tongue. Entire sections of the major hadith collections are devoted to speech, character, and etiquette (adab). The Prophet ﷺ declared that whoever guarantees what is between the jaws and what is between the loins will be guaranteed Paradise. True faith manifests not only in ritual devotion but in disciplined speech and moral restraint.

Equally serious is the responsibility of those who listen to backbiting. Hearing and entertaining such speech contaminates the heart and creates suspicion, even when the claims are doubtful. Surah al-Ḥujurāt (49:6) commands believers to verify information brought by a sinful person (fāsiq) lest harm be done out of ignorance.

To participate passively in backbiting is to share in its moral burden. Justice in Islam requires investigation, fairness, and the presumption of innocence. Standing firmly for truth—even against oneself, family, or close associates—is a defining mark of faith, as emphasized in Surah al-Nisā’ (4:135).

The violation becomes even more egregious when it involves spouses. Marriage is described in the Qur’an as a sacred trust, with each spouse serving as a garment for the other (2:187). A garment protects, covers, and dignifies. To expose, distort, or weaponize private matters is a betrayal of that trust.
