So We sent (plagues) on them: Wholesale death, Locusts, Lice, Frogs, And Blood: Signs openly self-explained: but they were steeped in arrogance,- a people given to sin. (7:133)

Every time the penalty fell on them, they said: "O Moses! on your behalf call on thy Lord in virtue of his promise to thee: If thou wilt remove the penalty from us, we shall truly believe in thee, and we shall send away the Children of Israel with thee." (7:134)

But every time We removed the penalty from them according to a fixed term which they had to fulfil,- Behold! they broke their word! (7:135)

So We exacted retribution from them: We drowned them in the sea, because they rejected Our Signs and failed to take warning from them. (7:136)

Ask them concerning the town standing close by the sea. Behold! they transgressed in the matter of the Sabbath. For on the day of their Sabbath their fish did come to them, openly holding up their heads, but on the day they had no Sabbath, they came not: thus did We make a trial of them, for they were given to transgression. (7:163)
