The Thunder - 13:11 (For each of them) there are those who watch him from in front of him and from behind him. They guard him by Allah´s command. Unless a community changes itself, Allah does not change their condition. And when Allah wills evil for a people, no power can stop it, nor do they have any protector except Him.
Generations destroyed before:
The Pilgrimage/22:42 If they belie you, so did the people of Noah, Ad and Thamud before them
The Pilgrimage/22:43 And the people of Abraham, and the people of Lot
The Pilgrimage/22:44 And the inhabitants of Median. Even Moses was denied. I gave the disbelievers a respite and then I called them to account; how is it that they do not recognize Me!

The Arabic Letter Sad/38:12 Before them were the people of Noah and the people of Ad and Pharaoh, the owner of the pyramids.
The Arabic Letter Sad/38:13 So did Thamud, the people of Lot and the Aykelites. They were parties.
The Arabic Letter Sad/38:14 They all denied the messengers and deserved My punishment.

The Letter Qaf/50:12 The people of Noah, the people of Res and Thamud had disbelieved before them.
The Letter Qaf/50:13 Ad, Pharaoh and the brothers of Lot.
The Letter Qaf/50:14 The people of Ayka and the people of Tubba´. They all denied the messengers. So My threat came true.

The Star/53:50 It is He who destroyed the ancient people of Ad,
The Star/53:52 And the people of Noah before him; they were very unjust and very unruly.
The Star/53:53 Those who were destroyed and submerged (Sodom and Gomorrah) were the most vulgar.
