A large part of the verses of the Quran are dedicated to telling the stories of the divine prophets, which, based on the Quranic principle of stabilizing the heart of the Messenger of Allah (PBUH), these historical events on the path of the mission have caused the steadfastness of the action and have influenced the hearts and souls of the audience. This research seeks to answer the question of how the story of Hazrat Lot (PBUH) in Surah An-Naml has caused the stabilization of the heart of the Prophet (PBUH). A descriptive-analytical study of this issue shows that God Almighty shows in the story of Lot (PBUH) in Surah An-Naml and in the difficult conditions of the tribes of Abu Talib that their unprecedented and ugly sin had become public and obvious, and knowing the displeasure of this act, they had rebelled against the divine commands, reaching a stage where the warnings of Lot (PBUH) were no longer suitable for them, but rather increased their rebellion, and distanced them from their nature. To the point where, contrary to their nature, they considered chastity and modesty a sin, and accused the pure followers of the divine prophets of pollution and expelled them from their homeland. But just as they committed an unprecedented disease, a devastating punishment descended on their false thoughts and actions.
