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 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 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 When in their insolence they transgressed (all) prohibitions, We said to them: "Be ye apes, despised and rejected." 166 And (remember) when thy Lord proclaimed that He would raise against them till the Day of Resurrection those who would lay on them a cruel torment. Lo! verily thy Lord is swift in prosecution and lo! verily He is Forgiving, Merciful. 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 Their descendants who inherited the Book gained (by bribery only) worthless things from the worldly life saying, "We shall be forgiven (for what we have done). They would have even doubled such gains if they could have received more. Did they not make a covenant (with God) in the Book not to speak any thing other than the Truth about God and to study its contents well? The life hereafter is much better for the pious ones. Will you not then think? 169 And those who hold fast to the Book, and have kept the prayer established; and We do not waste the wages of the righteous. 170 ۞ And [mention] when We raised the mountain above them as if it was a dark cloud and they were certain that it would fall upon them, [and Allah said], "Take what We have given you with determination and remember what is in it that you might fear Allah." 171
