According to search-discovered classical Islamic scholarship, Prophet Abraham, or Ibrahim (إبراهيم), stands as a paramount figure of unwavering monotheistic faith (Tawheed) and is honored with the unique title 'Khalilullah' (the Friend of Allah). The Quran, which mentions him by name 69 times, presents his life as the archetype of submission to God. The comprehensive tafsir of Ibn Kathir details his journey from logically rejecting the idolatry of his people to enduring immense trials, such as being cast into a fire and being commanded to sacrifice his son, with absolute trust in God. Al-Tabari provides the historical and linguistic context, while Al-Qurtubi explains the practical legacy of his actions, such as the establishment of the Kaaba with his son Ishmael as a center for pilgrimage. The synthesis of these scholarly traditions establishes Abraham not merely as a historical prophet but as the spiritual patriarch whose pure religion, 'Millat Ibrahim', is the foundation that all Muslims are called to follow.
