Al A’raf Ayah 163

وَسْــَٔلْهُمْ عَنِ ٱلْقَرْيَةِ ٱلَّتِى كَانَتْ حَاضِرَةَ ٱلْبَحْرِ إِذْ يَعْدُونَ فِى ٱلسَّبْتِ إِذْ تَأْتِيهِمْ حِيتَانُهُمْ يَوْمَ سَبْتِهِمْ شُرَّعًا وَيَوْمَ لَا يَسْبِتُونَ‌ۙ لَا تَأْتِيهِمْ‌ۚ كَذَٲلِكَ نَبْلُوهُم بِمَا كَانُواْ يَفْسُقُونَ ١٦٣ Ask them ?O Prophet? about ?the people of? the town which was by the sea, who broke the Sabbath. During the Sabbath, ?abundant? fish would come to them clearly visible, but on other days the fish were never seen. In this way We tested them for their rebelliousness.
