The Prophet (ﷺ) declared “I am the city of knowledge and Ali is its gate” (Hadith in Tirmidhi), establishing Hazrat Ali (RA) as “Bab-ul-Ilm”. This title acknowledges his unparalleled understanding of Quranic exegesis, jurisprudence, and prophetic traditions. Ali’s (RA) intellectual legacy includes the compilation of Nahjul Balagha, containing profound sermons on governance, theology, and ethics that remain studied worldwide. His legal judgments set precedents in Islamic jurisprudence.
