And ask the people of Moses concerning the town situated along the sea how its people profaned the Sabbath when fish came to them breaking the water's surface on Sabbath days, and would not come to them on other than Sabbath-days. Thus did We try them because of their disobedience. 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 And when they persisted in pursuing that which had been forbidden We said: 'Become despised apes.' 166 And your Lord declared He would send men against them who would inflict dreadful suffering on them till the Day of Doom, for your Lord is swift in retribution, though He is certainly forgiving and kind. 167 We dispersed them in groups over the earth, some righteous, some otherwise; and We tried them with good things and bad, that they may haply turn back. 168 Then there came after them an evil posterity who inherited the Book, taking only the frail good of this low life and saying: It will be forgiven us. And if the like good came to them, they would take it (too). Was not a promise taken from them in the Book that they would not speak anything about Allah but the truth, and they have read what is in it; and the abode of the hereafter is better for those who guard (against evil). Do you not then understand? 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
