Quran 7:177 from Surah Al-A'raaf on Divine Marvels.
سَآءَ مَثَلًا ٱلۡقَوۡمُ ٱلَّذِينَ كَذَّبُواْ بِـَٔايَٰتِنَا وَأَنفُسَهُمۡ كَانُواْ يَظۡلِمُونَ
English translation: Evil (as) an example (are) the people those who denied Our Signs and themselves they used to wrong
Transliteration: saa mathalan al-qawmu alladhina kadhabu biayatina wa-anfusahum kanu yazlimuna
