وَلُوطًا ءَاتَيْنَٰهُ حُكْمًۭا وَعِلْمًۭا وَنَجَّيْنَٰهُ مِنَ ٱلْقَرْيَةِ ٱلَّتِى كَانَت تَّعْمَلُ ٱلْخَبَٰٓئِثَ ۗ إِنَّهُمْ كَانُوا۟ قَوْمَ سَوْءٍۢ فَٰسِقِينَ
And unto Lot we gave judgment and knowledge, and We delivered him from the community that did abominations. Lo! they were folk of evil, lewd.
