Ask them about the town which was by the sea and what befell its people when they broke the Sabbath. On their Sabbath the fish came to them near the surface, but on week-days they never came near them -- thus We tried them because of their disobedience. 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 Therefore when they forgot what they had been reminded of, We saved those who had tried to prevent the doing of evil. And We meted out a severe punishment to the transgressors because they were rebellious. 165 and then, when they disdainfully persisted in doing what they had been forbidden to do, We said unto them: "Be as apes despicable!" 166 (Muhammad), consider, when your Lord declared to the (Israelites) His decision to raise a people above them who would make them suffer the worst kinds of torments until the Day of Judgment. Certainly your Lord's retribution is swift. He is All-forgiving and All-merciful. 167 We dispersed them through the earth in nations some were righteous, others were not, and tested them with good and evil in order that they return. 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 as to those who hold fast to the Book (i.e. act on its teachings) and perform As-Salat (Iqamat-as-Salat), certainly, We shall never waste the reward of those who do righteous deeds. 170 ۞ And [did We not say,] when We caused Mount Sinai to quake above the children of Israel as though it were a [mere] shadow, and they thought that it would fall upon them, "Hold fast with [all your] strength unto what We have vouchsafed you, and bear in mind all that is therein, so that you might remain conscious of God"? 171
