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 And when they forgot that whereof they had been reminded, We rescued those who forbade wrong, and visited those who did wrong with dreadful punishment because they were evil-livers. 165 When they crossed the limit of the prohibition, We made them turn into detested apes. 166 (Muhammad), consider, when your Lord declared to the (Israelites) His decision to raise a people above them who would make them suffer the worst kinds of torments until the Day of Judgment. Certainly your Lord's retribution is swift. He is All-forgiving and All-merciful. 167 And We divided them in the earth as separate groups; some of them are righteous and some are the other type; and We tested them with good (favours) and evil things (adversities) so that they may return. 168 And they have been succeeded by [new] generations who - [in spite of] having inherited the divine writ - clutch but at the fleeting good of this lower world and say: "We shall be forgiven, the while they are ready, if another such fleeting good should come their way, to clutch at it [and sin again]. Have they not been solemnly pledged through the divine writ not to attribute unto God aught but what is true, and [have they not] read again and again all that is therein? Since the life in the hereafter is the better [of the two] for all who are conscious of God - will you not, then, use your reason? 169 As to those who hold fast by the Book and establish regular prayer,- never shall We suffer the reward of the righteous to perish. 170 ۞ The day We shook the mountain above them like an awning, and they feared it would fall over them, (We said): "Hold fast to what We have given you, and bear in mind what is (said) therein so that you may take heed." 171
