The prohibition of deriding others is a cornerstone of Islamic ethics, explicitly detailed in the Quran and the teachings of the Prophet Muhammad. According to classical scholars such as Ibn Kathir, the Quranic verse 49:11 forbids believers from scoffing at, belittling, or humiliating others, as the person being ridiculed may hold a higher status in the sight of Allah. This injunction applies to both men and women and extends to defamation and the use of offensive nicknames. Furthermore, Surah Al-Humazah (104:1) issues a stern warning to every slanderer and fault-finder, promising a severe chastisement in the Hereafter. The terms 'humazah' and 'lumazah' describe a person who habitually insults, backbites, and creates discord among people through their speech and actions. This prohibition is rooted in the Islamic emphasis on the sanctity of a believer's honor and the promotion of a compassionate and cohesive society. Engaging in such behavior is seen as a manifestation of arrogance and a spiritually corrosive disease of the heart.
