(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 recall what time a community of them said: why exhort ye a people whom Allah is going to destroy or chastise with a severe chastisenent? They said: to justify us before your Lord, and that haply they may fear. 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 had scornfully persisted in what they had been forbidden, We said to them: 'Be apes, despised' 166 Then your Lord declared He would send against them he who would oppress them cruelly till the Day of Resurrection. Swift is the retribution of your Lord, yet surely He is Forgiving, the Most Merciful. 167 We divided them into nations on the earth; some are righteous and others are not. We tested them with well-being and hardship so that they might return (to the right path). 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 As for those who hold fast to the Book and are steadfast in prayer, We do not waste the wage of the righteous. 170 ۞ And when We shook the Mount above them as it were a covering, and they supposed that it was going to fall upon them (and We said): Hold fast that which We have given you, and remember that which is therein, that ye may ward off (evil). 171
