Surah Al-Baqarah — Ayah 65 (2:65)
وَلَقَدۡ عَلِمۡتُمُ ٱلَّذِينَ ٱعۡتَدَوۡاْ مِنكُمۡ فِي ٱلسَّبۡتِ فَقُلۡنَا لَهُمۡ كُونُواْ قِرَدَةً خَٰسِـِٔينَ ٦٥
English translation (Saheeh International)
And you had already known about those who transgressed among you concerning the sabbath, and We said to them, "Be apes, despised."
Brief commentary
You know well the story of your ancestors, who prepared to fish on the Sabbath when they were not allowed to do so, and did so through trickery. They set up nets in preparation for the Sabbath so Allah made them into monkeys, rejected and cast out, because of their trickery.
