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﴾.
