Quran 7:5 from Surah Al-A'raaf on Divine Marvels.
فَمَا كَانَ دَعۡوَىٰهُمۡ إِذۡ جَآءَهُم بَأۡسُنَآ إِلَّآ أَن قَالُوٓاْ إِنَّا كُنَّا ظَٰلِمِينَ
English translation: Then not was their plea when came to them Our punishment except that they said Indeed we were wrongdoers
Transliteration: fama kana da'wahum idh jaahum basuna illa an qalu inna kunna zalimina
