And ask thou them concerning the town that was close on the sea, when they transgressed in the matter of the sabt, when their fish came unto them openly on their sabt day, while they came not on the day whereon they kept not the sabt. Thus they were wont to transgress. 163 And when a community among them said, "Why do you advise [or warn] a people whom Allah is [about] to destroy or to punish with a severe punishment?" they [the advisors] said, "To be absolved before your Lord and perhaps they may fear Him." 164 Then, when they forgot what they had been exhorted, We delivered those who forbade evil and afflicted the wrong-doers with a grievous chastisement because of their evildoing. 165 When they persisted in doing what they had been forbidden, We said to them: "Become (like) apes despised." 166 And remember when your Lord announced the command that till the Day of Resurrection I will certainly send such oppressors against them, who will inflict them with a dreadful punishment; indeed your Lord is swift in meting out punishment; and indeed He is Oft Forgiving, Most Merciful. 167 We divided them into nations on the earth; some are righteous and others are not. We tested them with well-being and hardship so that they might return (to the right path). 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
