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 when a certain nation of them said, 'Why do you admonish a people God is about to destroy or to chastise with a terrible chastisement?' They said, 'As an excuse to your Lord; and haply they will be godfearing.' 164 Therefore when they forgot what they had been reminded of, We saved those who had tried to prevent the doing of evil. And We meted out a severe punishment to the transgressors because they were rebellious. 165 So when they were insolent about that which they had been forbidden, We said to them, "Be apes, despised." 166 And lo! Thy Sustainer made it known that most certainly He would rouse against them, unto Resurrection Day, people who would afflict them with cruel suffering: verily, thy Sustainer is swift in retribution - yet, verily, He is [also] much-forgiving, a dispenser of grace. 167 And We dispersed them through the earth in communities - some were righteous, others were not -and We tested them with prosperity and adversity that they may turn back (to righteousness). 168 After them succeeded an (evil) generation: They inherited the Book, but they chose (for themselves) the vanities of this world, saying (for excuse): "(Everything) will be forgiven us." (Even so), if similar vanities came their way, they would (again) seize them. Was not the covenant of the Book taken from them, that they would not ascribe to Allah anything but the truth? and they study what is in the Book. But best for the righteous is the home in the Hereafter. Will ye not understand? 169 Those who hold fast to the Book and establish Prayer - We shall not allow the reward of such righteous men to go to waste. 170 ۞ And [did We not say,] when We caused Mount Sinai to quake above the children of Israel as though it were a [mere] shadow, and they thought that it would fall upon them, "Hold fast with [all your] strength unto what We have vouchsafed you, and bear in mind all that is therein, so that you might remain conscious of God"? 171
