According to search-discovered classical Islamic scholarship, humility (التواضع - At-Tawadu') is a foundational virtue and a defining characteristic of a true believer. It is a comprehensive state that encompasses two dimensions: humility before Allah and humility towards creation. Ibn Kathir, in his tafsir on verses like 25:63, explains that the 'servants of the Most Merciful' are recognized by their gentle and humble demeanor, a direct result of their inner submission to God. The linguistic analysis of the root و-ض-ع (wa-da-'a), meaning 'to lower', confirms this understanding of consciously lowering one's ego. This virtue is not a sign of weakness but of spiritual strength, as the Prophet Muhammad (PBUH) stated, '...no person practices humility without God raising him in degrees.' The synthesis across more than 30 Quranic verses reveals that humility is essential for genuine worship (Khushu'), respectful relationships (especially with parents), and is the primary antidote to the destructive sin of arrogance (Kibr).
