According to search-discovered classical Islamic scholarship, the 'Sabbath-breakers' (أصحاب السبت - Ashab al-Sabat) refer to a community of the Children of Israel from a coastal town, as detailed in Quran 7:163-165. Tafsir by authorities like Ibn Kathir and Al-Tabari explains that Allah tested them by making fish conspicuously abundant on the Sabbath (Saturday), a day divinely consecrated for rest and worship, while scarce on weekdays. In an act of cunning disobedience, some members of the community devised tricks—such as setting nets on Friday to collect the trapped fish on Sunday—to circumvent the prohibition. This act of transgression split the community, with one group actively forbidding the evil, another remaining silent, and the third persisting in their sin. The Quranic narrative focuses on the divine judgment that followed, where Allah saved those who admonished the wrongdoers and inflicted a 'grievous chastisement' upon the transgressors, who were ultimately transformed into despised apes. This story serves as a profound cautionary tale on the futility of trying to deceive Allah, the severe consequences of violating divine commands, and the critical communal obligation to enjoin good and forbid evil.
