The Story of the People of the Prophet Lut
Allah the Exalted states,
كَذَّبَتْ قَوْمُ لُوطٍ بِالنُّذُرِ
The people of Lut denied the warnings.
Allah the Exalted states that the people of Lut defied and denied their Messenger and committed sodomy, the awful immoral sin that no people in the history of mankind had committed before. This is why Allah destroyed them with a type of torment that He never inflicted upon any nation before them. Allah the Exalted commanded Jibril, peace be upon him, to raise their cities to the sky and then turn them upside down over them, followed by stones made of marked Sijjil.
So He said here;
إِنَّا أَرْسَلْنَا عَلَيْهِمْ حَاصِبًا إِلاَّ الَ لُوطٍ
نَّجَّيْنَاهُم بِسَحَرٍ
