Quran 27:56 from Surah An-Naml on Divine Marvels.
۞فَمَا كَانَ جَوَابَ قَوۡمِهِۦٓ إِلَّآ أَن قَالُوٓاْ أَخۡرِجُوٓاْ ءَالَ لُوطٖ مِّن قَرۡيَتِكُمۡۖ إِنَّهُمۡ أُنَاسٞ يَتَطَهَّرُونَ
English translation: But not was (the) answer (of) his people except that they said Drive out (the) family (of) Lut from your town Indeed they (are) people who keep clean and pure
Transliteration: fama kana jawaba qawmihi illa an qalu akhriju ala lutin min qaryatikum innahum unasun yatatahharuna
