The word(s) "a'ad" appears 24 time(s) in 23 verse(s) in Quran in Muhammad Pickthal translation.

(11) And (the tribes of) a'ad and Thamud! (Their fate) is manifest unto you from their (ruined and deserted) dwellings. Satan made their deeds seem fair unto them and so debarred them from the Way, though they were keen observers.

(12) The folk of Noah before them denied (their messenger) and (so did the tribe of) a'ad, and Pharaoh firmly planted,

(13) A plight like that of Noah's folk, and a'ad and Thamud, and those after them, and Allah willeth no injustice for (His) slaves.

(14) But if they turn away, then say: I warn you of a thunderbolt like the thunderbolt (which fell of old upon the tribes) of a'ad and Thamud;

(15) As for a'ad, they were arrogant in the land without right, and they said: Who is mightier than us in power? Could they not see that Allah Who created them, He was mightier than them in power? And they denied Our revelations.

(16) And make mention (O Muhammad) of the brother of a'ad when he warned his folk among the wind-curved sandhills - and verily warners came and went before and after him - saying: Serve none but Allah. Lo! I fear for you the doom of a tremendous Day.

(17) And (the tribe of) a'ad, and Pharaoh, and the brethren of Lot,

(18) And in (the tribe of) a'ad (there is a portent) when we sent the fatal wind against them.

(19) And that He destroyed the former (tribe of) a'ad,

(20) (The tribe of) a'ad rejected warnings. Then how (dreadful) was My punishment after My warnings.
