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 a group of them questioned another group saying, "Why do you preach to those whom God has decided to destroy or punish by a severe torment?" they replied, "We preach to them for we are responsible in the sight of your Lord and so that perhaps they may have fear of God." 164 But when they forgot to remember the warning, We saved those who prohibited evil, but inflicted on the wicked a dreadful punishment -- requital for their disobedience. 165 So when they exceeded the limits of what they were prohibited, We said to them: "Be you monkeys, despised and rejected." (It is a severe warning to the mankind that they should not disobey what Allah commands them to do, and be far away from what He prohibits them). 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 split them up into sections on the earth. Some of them are righteous while some of them are otherwise, and We tested them with blessings and misfortunes, so that they might return to the right path. 168 Then there succeeded them a posterity; they inherited the Book, taking this near world's gear and saying: surety it will be forgiven. And if there cometh unto them gear like thereunto they shall take it. Hath there not lain upon them the bond of the Book that they shall not say of God aught but the truth? And they have read that which is therein. And the abode of the Hereafter is better for those who fear. Understand then ye not? 169 And those who hold fast by the Book and establish prayer - verily We shall not waste the hire of the rectifiers. 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
