Ask them about the town which was by the sea and what befell its people when they broke the Sabbath. On their Sabbath the fish came to them near the surface, but on week-days they never came near them -- thus We tried them because of their disobedience. 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 And thereupon, when those [sinners] had forgotten all that they had been told to take to heart, We saved those who had tried to prevent the doing of evil, and overwhelmed those who had been bent on evildoing with dreadful suffering for all their iniquity; 165 And then, when they disdainfully persisted in doing what they had been forbidden to do, We said to them, "Be as 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 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 Those who devote themselves to the teachings of the Book and are steadfast in prayer (should know that) the reward of those who reform themselves will not be lost. 170 ۞ And when We shook the mountain over them as if it were a covering overhead, and they thought that it was going to fall down upon them: Take hold of what We have given you with firmness, and be mindful of what is in it, so that you may guard (against evil). 171
