So Allah said;

﴿فَأَنجَيْنَـهُ وَالَّذِينَ مَعَهُ بِرَحْمَةٍ مِّنَّا وَقَطَعْنَا دَابِرَ الَّذِينَ كَذَّبُواْ بِـَايَـتِنَا وَمَا كَانُواْ مُؤْمِنِينَ ﴾

(So We saved him and those who were with him out of mercy from Us, and We severed the roots of those who belied Our Ayat; and they were not believers.) Allah mentioned several times in the Qur'an, the way the people of `Ad were destroyed stating that He sent a barren wind that destroyed everything it passed by. Allah said in another Ayah,

﴿وَأَمَّا عَادٌ فَأُهْلِكُواْ بِرِيحٍ صَرْصَرٍ عَاتِيَةٍ - سَخَّرَهَا عَلَيْهِمْ سَبْعَ لَيَالٍ وَثَمَـنِيَةَ أَيَّامٍ حُسُوماً فَتَرَى الْقَوْمَ فِيهَا صَرْعَى كَأَنَّهُمْ أَعْجَازُ نَخْلٍ خَاوِيَةٍ - فَهَلْ تَرَى لَهُم مِّن بَاقِيَةٍ ﴾

(And as for `Ad, they were destroyed by a furious violent wind! They were subjected to it for seven nights and eight days in succession, so that you could see men lying overthrown (destroyed), as if they were hollow trunks of date palms! Do you see any remnants of them) ﴿69:6-8﴾ When `Ad rebelled and transgressed, Allah destroyed them with a strong wind that carried them, one by one, up in the air and brought each one of them down on his head, thus smashing his head and severing it from its body. This is why Allah said,

﴿كَأَنَّهُمْ أَعْجَازُ نَخْلٍ خَاوِيَةٍ﴾

(as if they were hollow trunks of date palms!) ﴿69:7﴾ Muhammad bin Ishaq said that `Ad used to live in Yemen between Oman and Hadramawt. They also spread throughout the land and defeated various peoples, because of the strength that Allah gave them. They used to worship idols instead of Allah, and Allah sent to them Prophet Hud, peace be upon him. He was from their most common lineage and was the best among them in status. Hud commanded them to worship Allah Alone and associate none with him. He also ordered them to stop committing injustice against the people. But they rejected him and ignored his call. They said, `Who is stronger than us' Some of them, however, followed Hud, although they were few and had to conceal their faith. When `Ad defied the command of Allah, rejected His Prophet, committed mischief in the earth, became arrogant and built high palaces on every high place -- without real benefit to them -- Hud spoke to them, saying,

﴿أَتَبْنُونَ بِكُلِّ رِيعٍ ءَايَةً تَعْبَثُونَ ﴾

﴿وَتَتَّخِذُونَ مَصَانِعَ لَعَلَّكُمْ تَخْلُدُونَ - وَإِذَا بَطَشْتُمْ بَطَشْتُمْ جَبَّارِينَ فَاتَّقُواْ اللَّهَ وَأَطِيعُونِ ﴾

("Do you build high palaces on every high place, while you do not live in them And do you get for yourselves palaces (fine buildings) as if you will live therein forever. And when you seize (somebody), seize you (him) as tyrants Have Taqwa of Allah, and obey me.'') ﴿26:128-131﴾ However,

﴿قَالُواْ يَهُودُ مَا جِئْتَنَا بِبَيِّنَةٍ وَمَا نَحْنُ بِتَارِكِى ءالِهَتِنَا عَن قَوْلِكَ وَمَا نَحْنُ لَكَ بِمُؤْمِنِينَ إِن نَّقُولُ إِلاَّ اعْتَرَاكَ بَعْضُ ءَالِهَتِنَا بِسُوءٍ﴾

(They said: "O Hud! No evidence have you brought us, and we shall not leave our gods for your (mere) saying! And we are not believers in you. All that we say is that some of our gods have seized you with evil.'') meaning, madness,

﴿إِن نَّقُولُ إِلاَّ اعْتَرَاكَ بَعْضُ ءَالِهَتِنَا بِسُوءٍ قَالَ إِنِّى أُشْهِدُ اللَّهِ وَاشْهَدُواْ أَنِّى بَرِىءٌ مِّمَّا تُشْرِكُونَ - مِن دُونِهِ فَكِيدُونِى جَمِيعًا ثُمَّ لاَ تُنظِرُونِ - إِنِّى تَوَكَّلْتُ عَلَى اللَّهِ رَبِّى وَرَبِّكُمْ مَّا مِن دَآبَّةٍ إِلاَّ هُوَ ءاخِذٌ بِنَاصِيَتِهَآ إِنَّ رَبِّى عَلَى صِرَطٍ مُّسْتَقِيمٍ ﴾

(He said: "I call Allah to witness, and bear you witness that I am free from that which you associate with Him. So plot against me, all of you, and give me no respite. I put my trust in Allah, my Lord and your Lord! There is not a moving creature but He has the grasp of its forelock. Verily, my Lord is on the straight path (the truth).'') ﴿11:53-56﴾.''
