The document defines backbiting as saying something about another person that they dislike, whether it is true or not. Backbiting has negative social effects as it destroys respect and love for others. It is prohibited in Islam according to both the Quran and hadith. The Prophet described serious punishments for backbiting, including that it is a worse sin than adultery. The document provides ways to resist backbiting such as guarding one's tongue and opposing backbiting when one hears it.
