And ask them about the town which stood by the sea; when they exceeded the limits of the Sabbath, when their fish came to them on the day of their Sabbath, appearing on the surface of the water, and on the day on which they did not keep the Sabbath they did not come to them; thus did We try them because they transgressed. 163 And when a party of them said: Why do you admonish a people whom Allah would destroy or whom He would chastise with a severe chastisement? They said: To be free from blame before your Lord, and that haply they may guard (against evil). 164 When they disregarded the warnings that had been given them, We rescued those who forbade Evil; but We visited the wrong-doers with a grievous punishment because they were given to transgression. 165 When they crossed the limit of the prohibition, We made them turn into detested apes. 166 (Muhammad), consider, when your Lord declared to the (Israelites) His decision to raise a people above them who would make them suffer the worst kinds of torments until the Day of Judgment. Certainly your Lord's retribution is swift. He is All-forgiving and All-merciful. 167 And We have sundered them in the earth as (separate) nations. Some of them are righteous, and some far from that.

Will you not then think? 169 Those who devote themselves to the teachings of the Book and are steadfast in prayer (should know that) the reward of those who reform themselves will not be lost. 170 ۞ And when We shook the mountain over them as if it were a covering overhead, and they thought that it was going to fall down upon them: Take hold of what We have given you with firmness, and be mindful of what is in it, so that you may guard (against evil). 171
