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 When some of them said: "Why do ye preach to a people whom Allah will destroy or visit with a terrible punishment?"- said the preachers:" To discharge our duty to your Lord, and perchance 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 So when they took pride in that which they had been forbidden, We said unto them: Be ye apes despised and loathed! 166 And recall what time thy Lord proclaimed that he would surely raise upon them, till the Day of Resurrection, someone perpetrating upon them worst oppression. Verily thy Lord is swift in chastising, and verily He is Forgiving, Merciful. 167 And We cut them up on the earth into parties, (some) of them being righteous and (others) of them falling short of that, and We tried them with blessings and misfortunes that they might turn. 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 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
