..then how terrible was My rejection of them?

أَأَمِنتُم مَّن فِي السَّمَاءِ أَن يَخْسِفَ بِكُمُ الْأَرْضَ فَإِذَا هِيَ تَمُورُ  

أَمْ أَمِنتُم مَّن فِي السَّمَاءِ أَن يُرْسِلَ عَلَيْكُمْ حَاصِبًا ۖ فَسَتَعْلَمُونَ كَيْفَ نَذِيرِ  

وَلَقَدْ كَذَّبَ الَّذِينَ مِن قَبْلِهِمْ فَكَيْفَ كَانَ نَكِيرِ  

أَوَلَمْ يَرَوْا إِلَى الطَّيْرِ فَوْقَهُمْ صَافَّاتٍ وَيَقْبِضْنَ ۚ مَا يُمْسِكُهُنَّ إِلَّا الرَّحْمَٰنُ ۚ إِنَّهُ بِكُلِّ شَيْءٍ بَصِيرٌ  

أَمَّنْ هَٰذَا الَّذِي هُوَ جُندٌ لَّكُمْ يَنصُرُكُم مِّن دُونِ الرَّحْمَٰنِ ۚ إِنِ الْكَافِرُونَ إِلَّا فِي غُرُورٍ  

أَمَّنْ هَٰذَا الَّذِي يَرْزُقُكُمْ إِنْ أَمْسَكَ رِزْقَهُ ۚ بَل لَّجُّوا فِي عُتُوٍّ وَنُفُورٍ  

أَفَمَن يَمْشِي مُكِبًّا عَلَىٰ وَجْهِهِ أَهْدَىٰ أَمَّن يَمْشِي سَوِيًّا عَلَىٰ صِرَاطٍ مُّسْتَقِيمٍ  

قُلْ هُوَ الَّذِي أَنشَأَكُمْ وَجَعَلَ لَكُمُ السَّمْعَ وَالْأَبْصَارَ وَالْأَفْئِدَةَ ۖ قَلِيلًا مَّا تَشْكُرُونَ  

--

Do ye feel secure that He Who is in heaven will not cause you to be swallowed up by the earth when it shakes (as in an earthquake)?

Or do ye feel secure that He Who is in Heaven will not send against you a violent tornado (with showers of stones), so that ye shall know how (terrible) was My warning?

But indeed men before them rejected (My warning): then how (terrible) was My rejection (of them)?

Do they not observe the birds above them, spreading their wings and folding them in? None can uphold them except (Allah) Most Gracious: Truly (Allah) Most Gracious: Truly it is He that watches over all things.

Nay, who is there that can help you, (even as) an army, besides (Allah) Most Merciful? In nothing but delusion are the Unbelievers.

Or who is there that can provide you with Sustenance if He were to withhold His provision? Nay, they obstinately persist in insolent impiety and flight (from the Truth).

Is then one who walks headlong, with his face grovelling, better guided,- or one who walks evenly on a Straight Way?

Say: "It is He Who has created you (and made you grow), and made for you the faculties of hearing, seeing, feeling and understanding: little thanks it is ye give.

Surah al-Mulk [67:16-23]
