And ask them about that town which stood by the sea: how its people would profane the Sabbath whenever their fish came to them, breaking the water's surface, on a day on which they ought to have kept Sabbath - because they would not come to them on other than Sabbath-days! Thus did We try them by means of their [own] iniquitous doings. 163 And recall what time a community of them said: why exhort ye a people whom Allah is going to destroy or chastise with a severe chastisenent? They said: to justify us before your Lord, and that haply they may fear. 164 Then when they forgot that wherewith they had been exhorted, We delivered those who restrained from evil, and We laid hold of those who did wrong with a distressing torment for they were wont to transgress. 165 And then, when they disdainfully persisted in doing what they had been forbidden to do, We said to them, "Be as apes, despised!" 166 And [mention] when your Lord declared that He would surely [continue to] send upon them until the Day of Resurrection those who would afflict them with the worst torment. Indeed, your Lord is swift in penalty; but indeed, He is Forgiving and Merciful. 167 And We cut them up into communities on the earth; some of them righteous, and some of them otherwise; and We proved them with good and evil that haply they may return. 168 Their descendants who inherited the Book gained (by bribery only) worthless things from the worldly life saying, "We shall be forgiven (for what we have done). They would have even doubled such gains if they could have received more. Did they not make a covenant (with God) in the Book not to speak any thing other than the Truth about God and to study its contents well? The life hereafter is much better for the pious ones. Will you not then think? 169 And (as for) those who hold fast by the Book and keep up prayer, surely We do not waste the reward of the right doers. 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
