According to search-discovered classical Islamic scholarship, the concept of 'Overhearing the Host on High,' or *Istiraq al-Sam'* (استراق السمع), refers to the act of rebellious jinn (shayateen) attempting to eavesdrop on the celestial assembly of angels to steal fragments of divine decrees. The comprehensive analysis of Tafsir masters like Ibn Kathir and Al-Tabari across verses 15:18, 37:8, and 72:9 reveals this is not a myth but a core component of Islamic creed related to the protection of revelation (*wahy*). Before the advent of Prophet Muhammad (ﷺ), jinn could snatch some information and deliver it to soothsayers, mixing one truth with a hundred lies. However, the synthesis of these verses, particularly the direct testimony from the jinn in Surah Al-Jinn, shows that with the final revelation, the heavens were filled with 'stern guards' and 'flaming fires' (*shihab*). Now, any eavesdropper is pursued by a clear projectile, a mechanism that serves to completely safeguard the Quran's integrity and invalidate all forms of fortune-telling. This celestial guarding demonstrates Allah's absolute power and establishes the Quran as the pure, uncorrupted source of divine guidance.
