According to search-discovered classical Islamic scholarship, the principle of 'Respect for All' is a cornerstone of Islamic ethics (Akhlaq), rooted in the Quran's affirmation of universal human dignity (Karāmah, 17:70). This concept is most explicitly detailed in Surah Al-Hujurat (Chapter 49), which serves as a divine charter for social etiquette. Classical commentators like Ibn Kathir and Al-Qurtubi explain that verses 49:11-12 establish a sacred inviolability (Hurmah) for every individual's honor by strictly forbidding specific actions that erode respect: mockery (sukhriyah), defamation (lamz), offensive nicknames (tanabuz), excessive suspicion (zann), spying (tajassus), and backbiting (gheebah). The powerful metaphor of backbiting as 'eating the flesh of one's dead brother' highlights the severity of these sins. The linguistic analysis of these terms reveals their connection to the Arabic root for sanctity (ح-ر-م), positioning respect not merely as polite conduct but as a fundamental act of upholding the sacred trust of human honor, which is essential for a cohesive and compassionate society.
