According to search-discovered classical Islamic scholarship, the principle of believers being 'guides for one another' is rooted in the Quranic term 'Awliya' (أَوْلِيَاءُ), meaning allies, protectors, and supporters. Tafsir As-Sa'di explains that in Surah At-Tawbah 9:71, the phrase 'The believing men and believing women are allies of one another' establishes a foundational bond of love, support, and mutual belonging within the Ummah. This alliance is not merely a title but a functional reality defined by a set of collective responsibilities. Ibn Kathir clarifies that this relationship stands in direct contrast to the hypocrites, as believers actively 'enjoin what is right and forbid what is wrong'. Therefore, this mutual guidance is a communal duty, equally shared by men and women, that involves upholding Islamic pillars and collective obedience to Allah, which in turn becomes the basis for receiving Divine Mercy.
