The punishment of the Children of Israel who broke the Sabbath 7:163-167
7:163 Ask them about the village that overlooked the sea and what befell (its people) when they broke the Sabbath. Each Sabbath, their fish came swimming towards the shore, but on other days they did not come to them. As such We tempted them (the people) because they had done wrong.
7:164 And when some asked, 'Why do you admonish a nation whom Allah will destroy or sternly punish?' They replied, '(Seeking) a pardon from your Lord, and in order that they may be cautious.'
7:165 Therefore, when they forgot that of which they were reminded, We saved those who were forbidding evil, and seized the evildoers with an evil punishment for that which they used to do of evil.
7:167 Then your Lord declared He would send against them he who would oppress them cruelly till the Day of Resurrection. Swift is the retribution of your Lord, yet surely He is Forgiving, the Most Merciful.
