41:13 . But if they turn away , then say : I warn you of a thunderbolt like the thunderbolt ( which fell of old upon the tribes ) of Aad and Thamud ;
41:14 . When their messengers came unto them from before them and behind them , saying : Worship none but Allah! they said : If our Lord had willed , He surely would have sent down angels ( unto us ) , so lo! we are disbelievers in that wherewith ye have been sent .
41:15 . As for Aad , they were arrogant in the land without right , and they said : Who is mightier than us in power? Could they not see that Allah Who created them , He was mightier than them in power? And they denied Our revelations .
41:16 . Therefor We let loose on them a raging wind in evil days , that We might make them taste the torment of disgrace in the life of the world . And verily the doom of the Hereafter will be more shameful , and they will not be helped .
