In the manner of the people of Firon and those before them; they disbelieved in Allah's communications, therefore Allah destroyed them on account of their faults; surely Allah is strong, severe in requiting (evil).

And messengers before you were certainly mocked at, but I gave respite to those who disbelieved, then I destroyed them; how then was My requital (of evil)?

That was because there came to them their messengers with clear arguments, but they rejected (them), therefore Allah destroyed them; surely He is Strong, Severe in retribution.
