According to the foundational teachings of Islam, the 'Basic tenets' are authentically known as the Six Pillars of Faith (Arkān al-Īmān). These pillars represent the core of a Muslim's creed (Aqidah) and are definitively outlined in the celebrated Hadith of Gabriel. Classical commentators, particularly Imam an-Nawawi in his explanation of this hadith, affirm that these tenets form an indivisible foundation for a believer's entire worldview. The six pillars are: the belief in the absolute Oneness of Allah; His Angels; His revealed Books (like the Quran); His Messengers; the Day of Judgment; and the Divine Decree (Qadar). While not enumerated in a single verse, the Quran provides the basis for each pillar in verses such as 2:285 and 4:136, which classical scholars like Ibn Kathir synthesize to demonstrate their scriptural authority. This synthesis establishes that Arkān al-Īmān is not merely a list of beliefs, but a comprehensive and interconnected framework that provides spiritual security and guides a Muslim's actions and purpose.
