﴿ وَمَا كَانَ جَوَابَ قَوْمِهِۦٓ إِلَّآ أَن قَالُوٓا۟ أَخْرِجُوهُم مِّن قَرْيَتِكُمْ ۖ إِنَّهُمْ أُنَاسٌۭ يَتَطَهَّرُونَ ﴾

“But his people's only answer was this: "Expel them from your land! Verily, they are folk who make themselves out to be pure!””

إِنَّهُمْ أُنَاسٌ يَتَطَهَّرُونَ ("These are indeed men who want to be pure (from sins)!") Qatadah commented, "They shamed them (Lut and the believers) with what is not a shame at all." Mujahid commented, "(Lut's people said about Lut and the believers,) They are a people who want to be pure from men's anuses and women's anuses!" Similar was narrated from Ibn `Abbas.
