(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 When a group of them questioned another group saying, "Why do you preach to those whom God has decided to destroy or punish by a severe torment?" they replied, "We preach to them for we are responsible in the sight of your Lord and so that perhaps they may have fear of God." 164 Then, when they forgot what they had been exhorted, We delivered those who forbade evil and afflicted the wrong-doers with a grievous chastisement because of their evildoing. 165 So when they were insolent about that which they had been forbidden, We said to them, "Be apes, despised." 166 Behold! thy Lord did declare that He would send against them, to the Day of Judgment, those who would afflict them with grievous penalty. Thy Lord is quick in retribution, but He is also Oft-forgiving, Most Merciful. 167 And We cut them up into communities on the earth; some of them righteous, and some of them otherwise; and We proved them with good and evil that haply they may return. 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 But those who hold fast to the Book and establish prayer - indeed, We will not allow to be lost the reward of the reformers. 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
