A significant portion of the Qurʾānic verses is dedicated to narrating the stories of the divine prophets. According to the Qurʾānic principle of consolidating the heart of the Messenger of God (PBUH), these historical events, encountered during the prophetic mission, served to strengthen resolve in action and to influence the hearts and minds of the audience. This research endeavors to answer the question: How did the story of Prophet Lot (PBUH) in Surah An-Naml contribute to the consolidation of the heart of the Prophet (PBUH)? A descriptive-analytical examination of this issue reveals that in the narrative of Prophet Lot (PBUH) in Surah An-Naml, and during the arduous conditions of the Shiʿb Abī Ṭālib boycott, the Exalted God illustrates how his people, who had committed an unprecedented and heinous sin openly and visibly and despite knowing the reprehensibility of their actions had become so rebellious against divine commandments that Lot’s (PBUH) warnings were no longer heeded. Instead, their defiance intensified, alienating them from their innate disposition. To such an extent that, contrary to their very nature, they considered chastity and purity a sin, accused the virtuous followers of the divine prophets of corruption, and expelled them from their homeland. However, just as they succumbed to an unprecedented malady, a devastating punishment descended upon their erroneous thoughts and deeds.
