Ask them (O Muhammad) of the township that was by the sea, how they did break the Sabbath, how their big fish came unto them visibly upon their Sabbath day and on a day when they did not keep Sabbath came they not unto them. Thus did We try them for that they were evil-livers. 163 And when a community among them said: Why preach ye to a folk whom Allah is about to destroy or punish with an awful doom, they said: In order to be free from guilt before your Lord, and that haply they may ward off (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 And when they had scornfully persisted in what they had been forbidden, We said to them: 'Be apes, despised' 166 Behold! thy Lord did declare that He would send against them, to the Day of Judgment, those who would afflict them with grievous penalty. Thy Lord is quick in retribution, but He is also Oft-forgiving, Most Merciful. 167 We broke them up into sections on this earth. There are among them some that are the righteous, and some that are the opposite. We have tried them with both prosperity and adversity: In order that they might turn (to us). 168 Then others succeeded them who inherited the Book and availed themselves of the vanities of this lower world, saying: 'It will be forgiven us' But if similar vanities came their way, they would again take them. Have they not taken the covenant of the Book, which they have studied, to tell nothing of Allah except what is true? Surely, the Everlasting Life is better for the cautious, do you not understand! 169 And those who hold fast to the Book, and perform the prayer -- surely We leave not to waste the wage of those who set aright. 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
