It is narrated about Hasan that he recited the entire verse { وَاسْأَلْہُمْ عَنِ الْقَرْیَۃِ الَّتِی کَانَتْ حَاضِرَۃَ الْبَحْرِ إذْ یَعْدُونَ فِی السَّبْتِ إذْ تَأْتِیہِمْ حِیتَانُہُمْ یَوْمَ سَبْتِہِمْ شُرَّعًا }. Then he said: This was a fish which Allah Almighty had forbidden them for one day, and besides that, on the remaining days, He had made it lawful for the people. So these fish would come to them on that day like pregnant she-camels. They would not stop anyone. So those people intended and began to restrain (them), until they would catch them and then eat them. By God! There is no food greater than this food that people have ever eaten. It brought disgrace in this world and the severest punishment in the Hereafter. And by God! A believer is more sacred to God than a fish. But Allah Almighty has promised the people the Day of Resurrection, and the Resurrection is more dreadful and certain to occur.
