Allah says, just as We sent Nuh to his people, similarly, to the `Ad people, We sent Hud one of their own brethren. Muhammad bin Ishaq said that the tribe of `Ad were the descendants of `Ad, son of Iram, son of `Aws, son of Sam, son of Nuh. I say, these are indeed the ancient people of `Ad whom Allah mentioned, the children of `Ad, son of Iram who were living in the deserts with lofty pillars or statues. Allah said,

[أَلَمْ تَرَ كَيْفَ فَعَلَ رَبُّكَ بِعَادٍ - إِرَمَ ذَاتِ الْعِمَادِ - الَّتِى لَمْ يُخْلَقْ مِثْلُهَا فِى الْبِلَـدِ ]

(Have you not seen how your Lord dealt with `Ad (people). Of Iram like (lofty) pillars. The like of which were not created in the land) [89:6-8] because of their might and strength. Allah said in another instance,

[فَأَمَّا عَادٌ فَاسْتَكْبَرُواْ فِى الاٌّرْضِ بِغَيْرِ الْحَقِّ وَقَالُواْ مَنْ أَشَدُّ مِنَّا قُوَّةً أَوَلَمْ يَرَوْاْ أَنَّ اللَّهَ الَّذِى خَلَقَهُمْ هُوَ أَشَدُّ مِنْهُمْ قُوَّةً وَكَانُواْ بِـَايَـتِنَا يَجْحَدُونَ ]

(As for `Ad, they were arrogant in the land without right, and they said: "Who is mightier than us in strength'' See they not that Allah Who created them was mightier in strength than them. And they used to deny Our Ayat!) [41:15].
