163. Ask the Jews about how Allah punished some of the Israelites. Remind them of the story of the town which was near to the sea where they used to overstep the limits of Allah: fishing on the Sabbath after they had been forbidden from doing so. Allah tested them by making the fish come to them so that they could see them clearly on the surface of the sea on Saturday, and then making them disappear from view during the rest of the week. Allah gave them this trial because of their disobedience and wrongdoing. So eventually they decided to fish by setting up their nets thereby using a trick, so that the fish would fall into them on Saturday and they could take them and eat them on Sunday.
