Shaddād (Arabic: شدّاد), also known as Shaddād bin ʽĀd (شدّاد بن عاد), was believed to be the king of the lost Arabian city of Iram of the Pillars, an account of which is mentioned in Sura 89 of the Qur'an.
Brothers Shadīd (شديد) and Shaddād are said to have reigned in turn over the 1,000 Adite tribes, each consisting of several thousand men.
Many Arab writers tell of an expedition of Shaddād that caused the Canaanite migration, their settling in Syria, and the Shepherd invasion of Egypt.
According to the Quran, Iram of the Pillars was a city of occult worshippers of stone idols, who defied the warnings of the prophet Hud.
But the people would not repent, so they were destroyed by a furious wind, from which only prophet Hud and a few believers emerged.
