According to the consensus of classical Islamic scholarship, the principle of men's conduct toward women is significantly shaped by the Quranic command in Surah An-Nur, verse 30, to 'lower the gaze' (ghadd al-basar) and 'guard the private parts' (hifz al-furuj). This directive is not merely about physical aversion of the eyes but is a comprehensive approach to cultivating inner purity and modesty (*haya*). Ibn Kathir explains that this is a command from Allah for believing men to refrain from looking at what is forbidden, thereby protecting their hearts from temptation. Al-Qurtubi emphasizes the societal benefit of this practice, as it fosters an environment of respect and dignity, preventing the objectification of women. The linguistic analysis of 'ghadd' suggests a restraining and reducing of one's gaze, rather than complete avoidance of looking, which allows for necessary interactions in daily life. This principle is a proactive measure that, when practiced sincerely, leads to what the Quran describes as 'greater purity' (*azka lahum*), strengthening a man's faith and his relationship with Allah. It is the first step in a holistic system of modesty that also includes directives for women, creating a balanced and respectful social fabric.
