Surah الأعرافVerse 82 of 206
وَمَا كَانَ جَوَابَ قَوْمِهِ إِلَّا أَن قَالُواْ أَخْرِجُوهُم مِّن قَرْيَتِكُمْ إِنَّهُمْ أُنَاسٌ يَتَطَهَّرُونَ
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.
