The Heights - 7:5 "When Our torment came to them, they had no words but to say: "Indeed, we were wrongdoers"."
Generations destroyed before:
The Pilgrimage/22:42 If they belie you, so did the people of Noah, Ad and Thamud before them
وَاِنْ يُكَذِّبُوكَ فَقَدْ كَذَّبَتْ قَبْلَهُمْ قَوْمُ نُوحٍ وَعَادٌ وَثَمُودُۙ
The Pilgrimage/22:43 And the people of Abraham, and the people of Lot
وَقَوْمُ اِبْرٰه۪يمَ وَقَوْمُ لُوطٍۙ
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!
وَاَصْحَابُ مَدْيَنَۚ وَكُذِّبَ مُوسٰى فَاَمْلَيْتُ لِلْكَافِر۪ينَ ثُمَّ اَخَذْتُهُمْۚ فَكَيْفَ كَانَ نَك۪يرِ

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.
كَذَّبَتْ قَبْلَهُمْ قَوْمُ نُوحٍ وَعَادٌ وَفِرْعَوْنُ ذُوالْاَوْتَادِۙ
The Arabic Letter Sad/38:13 So did Thamud, the people of Lot and the Aykelites. They were parties.
وَثَمُودُ وَقَوْمُ لُوطٍ وَاَصْحَابُ لْـَٔيْكَةِۜ اُو۬لٰٓئِكَ الْاَحْزَابُ
The Arabic Letter Sad/38:14 They all denied the messengers and deserved My punishment.
اِنْ كُلٌّ اِلَّا كَذَّبَ الرُّسُلَ فَحَقَّ عِقَابِ۟

The Letter Qaf/50:12 The people of Noah, the people of Res and Thamud had disbelieved before them.
كَذَّبَتْ قَبْلَهُمْ قَوْمُ نُوحٍ وَاَصْحَابُ الرَّسِّ وَثَمُودُۙ
The Letter Qaf/50:13 Ad, Pharaoh and the brothers of Lot.
وَعَادٌ وَفِرْعَوْنُ وَاِخْوَانُ لُوطٍۙ
The Letter Qaf/50:14 The people of Ayka and the people of Tubba´. They all denied the messengers. So My threat came true.
وَاَصْحَابُ الْاَيْكَةِ وَقَوْمُ تُبَّعٍۜ كُلٌّ كَذَّبَ الرُّسُلَ فَحَقَّ وَع۪يدِ

The Star/53:50 It is He who destroyed the ancient people of Ad,
وَاَنَّـهُٓ اَهْلَكَ عَاداًۨ الْاُو۫لٰىۙ
The Star/53:52 And the people of Noah before him; they were very unjust and very unruly.
وَقَوْمَ نُوحٍ مِنْ قَبْلُۜ اِنَّهُمْ كَانُوا هُمْ اَظْلَمَ وَاَطْغٰىۜ
The Star/53:53 Those who were destroyed and submerged (Sodom and Gomorrah) were the most vulgar.
وَالْمُؤْتَفِكَةَ اَهْوٰىۙ
