According to search-discovered classical Islamic scholarship, the act of Prophet Lut's people—men approaching men with sexual desire—is unequivocally defined in the Quran as a 'Fahisha,' a term signifying a grave, shameful, and lewd evil. Esteemed commentators like Ibn Kathir and Al-Qurtubi explain that the Quran emphasizes the unique gravity of this transgression by stating it was an abomination 'as no one has preceded you with from among the worlds' (Quran 7:80). This highlights its status as an unprecedented deviation from the natural order (fitrah) established by Allah. The verses (26:165-166) further characterize the act as a transgression ('aduun) for abandoning the wives Allah created for them. The scholarly consensus is that this 'Fahisha' specifically refers to sodomy, a practice that was a hallmark of the corruption of Lut's people and a primary reason for their divine punishment.
