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!"
Ith jaathumu alrrusulu min bayni aydeehim wamin khalfihim alla taAAbudoo illa Allaha qaloo law shaa rabbuna laanzala malaikatan fainna bima orsiltum bihi kafiroona
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)."
Faamma AAadun faistakbaroo fee alardi bighayri alhaqqi waqaloo man ashaddu minna quwwatan awalam yaraw anna Allaha allathee khalaqahum huwa ashaddu minhum quwwatan wakanoo biayatina yajhadoona
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!
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.
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.
