According to search-discovered classical Islamic scholarship, the concept of Isti'adha, or seeking refuge, is a fundamental act of worship that affirms a believer's absolute dependence on Allah for protection from all evil. This practice is epitomized in the final two chapters of the Quran, Surah Al-Falaq and Surah An-Nas, collectively known as Al-Mu'awwidhatayn (the two chapters of refuge). Ibn Kathir explains that these chapters were revealed as a divine remedy and shield against both external threats—such as the evil of creation, darkness, sorcery, and envy—and the primary internal threat of the whisperings of Satan (waswas). Al-Qurtubi emphasizes the practical application of reciting these chapters for daily protection. The linguistic analysis of the term Isti'adha, from the root 'awtha, signifies a conscious act of fleeing from something one fears to a source of ultimate protection. The synthesis of scholarly interpretations across the provided verses establishes Isti'adha not merely as a verbal utterance, but as a profound state of the heart that strengthens faith, purifies intention, and builds a fortress around the believer's spiritual and physical well-being.
