According to search-discovered classical Islamic scholarship, Thunder (رعد - Ar-Ra'd) is a profound sign (ayah) of Allah's omnipotence and majesty. The Quran, particularly in the chapter named after it, Surah Ar-Ra'd, elevates thunder from a mere natural phenomenon to an active glorifier of the Divine. Verse 13:13 states, "And the thunder exalts [Allah] with praise of Him – and the angels [as well] from fear of Him." Classical commentators like Ibn Kathir and others have discussed narrations suggesting that thunder is an angel responsible for directing the clouds, or its sound is the angel's voice. This interpretation coexists with the understanding of it as a natural process, as all of nature is ultimately governed by angels carrying out Allah's will. Thematically, thunder embodies a powerful duality: it inspires fear of Allah's might and potential punishment, often preceding thunderbolts, while also heralding the hope of life-giving rain and mercy. This duality is also used metaphorically in Surah Al-Baqarah (2:19), where thunder represents the terrifying warnings of the Quran to the hypocrites. The prescribed supplications upon hearing thunder transform this awesome event into a conscious act of remembrance and an acknowledgment of Allah's absolute sovereignty over all of creation.
