(Muhammad), ask them about the (people of the) towns on the seashore. They had transgressed by catching fish on the Sabbath. Each Sabbath the fish came openly within their reach but not so on other days. Thus, We were testing them because of their evil deeds. 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 So, when they forgot that they were reminded of; We delivered those who were forbidding wickedness, and We seized the evildoers with evil chastisement for their ungodliness. 165 So when they exceeded the bounds of that which they were prohibited We said unto them: be ye apes despised. 166 And when Thy Lord proclaimed He would send forth against them, unto the Day of Resurrection, those who should visit them with evil chastisement. Surely thy Lord is swift in retribution; surely He is All-forgiving, All-compassionate. 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 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
