The Quran specifically refers to the people of 'Äd (ÙÙÙ Űčۧۯ) as a nation of immense physical size and power.
The Quran mentions their boastful question: "Who is greater than us in strength?" (Surah Fussilat, 41:15), highlighting their arrogance based on their military and construction might, a challenge that was met with divine punishment.
