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 And when a community among them said: "Why do you preach to a people whom Allah is about to destroy or to punish with a severe torment?" (The preachers) said: "In order to be free from guilt before your Lord (Allah), and perhaps they may fear Allah." 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 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 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 We broke them up into sections on this earth. There are among them some that are the righteous, and some that are the opposite. We have tried them with both prosperity and adversity: In order that they might turn (to us). 168 After them succeeded an (evil) generation: They inherited the Book, but they chose (for themselves) the vanities of this world, saying (for excuse): "(Everything) will be forgiven us." (Even so), if similar vanities came their way, they would (again) seize them. Was not the covenant of the Book taken from them, that they would not ascribe to Allah anything but the truth? and they study what is in the Book. But best for the righteous is the home in the Hereafter. Will ye not understand? 169 And those who hold fast by the Book and establish prayer - verily We shall not waste the hire of the rectifiers. 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
