According to search-discovered prophetic tradition and classical Islamic scholarship, the Six Articles of Faith (أركان الإيمان, Arkan al-Iman) are the foundational tenets of Islamic creed (Aqeedah). Explicitly defined by the Prophet Muhammad ﷺ in the celebrated Hadith of Gabriel, these articles constitute the very essence of Iman (Faith): Belief in the absolute Oneness of Allah (Tawhid); Belief in His Angels (Malaikah); Belief in His revealed Books (Kutub); Belief in His Messengers (Rusul); Belief in the Day of Judgment (Yawm al-Qiyamah); and Belief in the Divine Decree (Qadar). While the Quran provides the foundation for each article individually across numerous verses (e.g., 2:285, 4:136), the Hadith of Gabriel provides the definitive, synthesized list. Classical scholars like Ibn Kathir and Al-Qurtubi unanimously affirm that these six beliefs are indivisible and form the necessary core conviction for a person to be considered a believer (Mumin). This framework distinguishes inward faith from outward actions (the Five Pillars of Islam), establishing the theological worldview that gives meaning to a Muslim's life and practice.
