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 So when they exceeded the bounds of that which they were prohibited We said unto them: be ye apes despised. 166 Then your Lord declared that, until the Day of Resurrection, He would send others against them to inflict terrible suffering on them. Your Lord is swift in retribution; yet surely He is most forgiving and merciful. 167 And We cut them up on the earth into parties, (some) of them being righteous and (others) of them falling short of that, and We tried them with blessings and misfortunes that they might turn. 168 They were succeeded by generations who inherited the Scripture and took to the fleeting gains of this world, saying, "We shall certainly be forgiven." If there came to them similar fleeting gains again, they would take them. Was a pledge not taken from them, written in the Scripture, that they would not say anything but the truth about God? And they have studied whatever is in it. Surely the Home of the Hereafter is better for those who fear Him. Will you not understand? 169 For [We shall requite] all those who hold fast to the divine writ and are constant in prayer: verily, We shall not fail to requite those who enjoin the doing of what is right! 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
