Surah Al-A'raf, ayah 163

7:163

وَسۡـَٔلۡهُمۡ عَنِ ٱلۡقَرۡيَةِ ٱلَّتِي كَانَتۡ حَاضِرَةَ ٱلۡبَحۡرِ إِذۡ يَعۡدُونَ فِي ٱلسَّبۡتِ إِذۡ تَأۡتِيهِمۡ حِيتَانُهُمۡ يَوۡمَ سَبۡتِهِمۡ شُرَّعٗا وَيَوۡمَ لَا يَسۡبِتُونَ لَا تَأۡتِيهِمۡۚ كَذَٰلِكَ نَبۡلُوهُم بِمَا كَانُواْ يَفۡسُقُونَ ١٦٣

Was'alhum 'anil-qaryatil-latī kānat hādiratal-bahri idh ya'dūna fis-sabti idh ta'tīhim hītānuhum yawma sabtihim shurra'an wayawma lā yasbitūna lā ta'tīhim kadhālika nablūhum bimā kānū yafsuqūn

And ask them about the town that was by the sea - when they transgressed in [the matter of] the sabbath - when their fish came to them openly on their sabbath day, and the day they had no sabbath they did not come to them. Thus did We give them trial because they were defiantly disobedient.
