فَإِنْ أَعْرَضُوا فَقُلْ أَنْذَرْتُكُمْ صَاعِقَةً مِثْلَ صَاعِقَةِ عَادٍ وَثَمُودَ ١٣
But if they turn away, say thou: "I have warned you of a stunning Punishment (as of thunder and lightning) like that which (overtook) the 'Ad and the Thamud!"
41:14
إِذْ جَاءَتْهُمُ الرُّسُلُ مِنْ بَيْنِ أَيْدِيهِمْ وَمِنْ خَلْفِهِمْ أَلَّا تَعْبُدُوا إِلَّا اللَّهَ ۖ قَالُوا لَوْ شَاءَ رَبُّنَا لَأَنْزَلَ مَلَائِكَةً فَإِنَّا بِمَا أُرْسِلْتُمْ بِهِ كَافِرُونَ ١٤
Behold, the messengers came to them, from before them and behind them, (preaching): "Serve none but Allah." They said, "If our Lord had so pleased, He would certainly have sent down angels (to preach). Now we reject your mission (altogether)."
41:15
فَأَمَّا عَادٌ فَاسْتَكْبَرُوا فِي الْأَرْضِ بِغَيْرِ الْحَقِّ وَقَالُوا مَنْ أَشَدُّ مِنَّا قُوَّةً ۖ أَوَلَمْ يَرَوْا أَنَّ اللَّهَ الَّذِي خَلَقَهُمْ هُوَ أَشَدُّ مِنْهُمْ قُوَّةً ۖ وَكَانُوا بِآيَاتِنَا يَجْحَدُونَ ١٥
Now the 'Ad behaved arrogantly through the land, against (all) truth and reason, and said: "Who is superior to us in strength?" What! did they not see that Allah, Who created them, was superior to them in strength? But they continued to reject Our Signs!
41:16
فَأَرْسَلْنَا عَلَيْهِمْ رِيحًا صَرْصَرًا فِي أَيَّامٍ نَحِسَاتٍ لِنُذِيقَهُمْ عَذَابَ الْخِزْيِ فِي الْحَيَاةِ الدُّنْيَا ۖ وَلَعَذَابُ الْآخِرَةِ أَخْزَىٰ ۖ وَهُمْ لَا يُنْصَرُونَ ١٦
So We sent against them a furious Wind through days of disaster, that We might give them a taste of a Penalty of humiliation in this life; but the Penalty of a Hereafter will be more humiliating still: and they will find no help.
41:17
وَأَمَّا ثَمُودُ فَهَدَيْنَاهُمْ فَاسْتَحَبُّوا الْعَمَىٰ عَلَى الْهُدَىٰ فَأَخَذَتْهُمْ صَاعِقَةُ الْعَذَابِ الْهُونِ بِمَا كَانُوا يَكْسِبُونَ ١٧
As to the Thamud, We gave them Guidance, but they preferred blindness (of heart) to Guidance: so the stunning Punishment of humiliation seized them, because of what they had earned.
