Quran 41:15 from Surah Fussilat on Divine Marvels.
فَأَمَّا عَادٞ فَٱسۡتَكۡبَرُواْ فِي ٱلۡأَرۡضِ بِغَيۡرِ ٱلۡحَقِّ وَقَالُواْ مَنۡ أَشَدُّ مِنَّا قُوَّةًۖ أَوَلَمۡ يَرَوۡاْ أَنَّ ٱللَّهَ ٱلَّذِي خَلَقَهُمۡ هُوَ أَشَدُّ مِنۡهُمۡ قُوَّةٗۖ وَكَانُواْ بِـَٔايَٰتِنَا يَجۡحَدُونَ

Transliteration: fa-amma adun fa-is'takbaru fi al-ardi bighayri al-haqi waqalu man ashaddu minna quwwatan awalam yaraw anna al-laha alladhi khalaqahum huwa ashaddu min'hum quwwatan wakanu biayatina yajhaduna
