(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 certain nation of them said, 'Why do you admonish a people God is about to destroy or to chastise with a terrible chastisement?' They said, 'As an excuse to your Lord; and haply they will be godfearing.' 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 When they persisted in doing what they had been forbidden, We said to them: "Become (like) apes despised." 166 And lo! Thy Sustainer made it known that most certainly He would rouse against them, unto Resurrection Day, people who would afflict them with cruel suffering: verily, thy Sustainer is swift in retribution - yet, verily, He is [also] much-forgiving, a dispenser of grace. 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 after them a new generation inherited the Book. They took to the things of this base world, and said: "We shall (surely) be forgiven this." Yet they will accept similar things if they came their way again. Had they not been covenanted in the Book to say nothing in the name of God but the truth? And they have read this in it. The abode of the life to come is better for those who fear God. Can they not comprehend? 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 ۞ The day We shook the mountain above them like an awning, and they feared it would fall over them, (We said): "Hold fast to what We have given you, and bear in mind what is (said) therein so that you may take heed." 171
