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 when a community among them said: "Why do you preach to a people whom Allah is about to destroy or to punish with a severe torment?" (The preachers) said: "In order to be free from guilt before your Lord (Allah), and perhaps they may fear Allah." 164 When they (the unjust people) forgot what was preached to them, We saved the preachers from evil and afflicted the unjust for their evil deeds, with a dreadful torment. 165 And when they turned in disdain from that forbidding We said to them, 'Be you apes, miserably slinking!' 166 And [mention] when your Lord declared that He would surely [continue to] send upon them until the Day of Resurrection those who would afflict them with the worst torment. Indeed, your Lord is swift in penalty; but indeed, He is Forgiving and Merciful. 167 And We have broken them (i.e. the Jews) up into various separate groups on the earth, some of them are righteous and some are away from that. And We tried them with good (blessings) and evil (calamities) in order that they might turn (to Allah's Obedience). 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 As to those who hold fast by the Book and establish regular prayer,- never shall We suffer the reward of the righteous to perish. 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
