Surah Al-A'raaf, Verse 163
وَسْـَٔلْهُمْ عَنِ ٱلْقَرْيَةِ ٱلَّتِى كَانَتْ حَاضِرَةَ ٱلْبَحْرِ إِذْ يَعْدُونَ فِى ٱلسَّبْتِ إِذْ تَأْتِيهِمْ حِيتَانُهُمْ يَوْمَ سَبْتِهِمْ شُرَّعًۭا وَيَوْمَ لَا يَسْبِتُونَ ۙ لَا تَأْتِيهِمْ ۚ كَذَٰلِكَ نَبْلُوهُم بِمَا كَانُوا۟ يَفْسُقُونَ
Translation — Sahih International
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.
