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 some of them asked, "Why do you admonish a people whom God is going to destroy or to afflict with a severe punishment?" They answered, "In order to be free from blame before your Lord, and that they may perhaps fear Him." 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 when they persisted in pursuing that which had been forbidden We said: 'Become despised apes.' 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 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 Then others succeeded them who inherited the Book and availed themselves of the vanities of this lower world, saying: 'It will be forgiven us' But if similar vanities came their way, they would again take them. Have they not taken the covenant of the Book, which they have studied, to tell nothing of Allah except what is true? Surely, the Everlasting Life is better for the cautious, do you not understand! 169 And (as for) those who hold fast by the Book and keep up prayer, surely We do not waste the reward of the right doers. 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
