﴿ وَعَلَى ٱلَّذِينَ هَادُوا۟ حَرَّمْنَا مَا قَصَصْنَا عَلَيْكَ مِن قَبْلُ ۖ وَمَا ظَلَمْنَٰهُمْ وَلَٰكِن كَانُوٓا۟ أَنفُسَهُمْ يَظْلِمُونَ ﴾

“And [only] unto those who followed the Jewish faith did We forbid all that We have mentioned to thee ere this; and no wrong did We do to them, but it was they who persistently wronged themselves.”

(And unto those who are Jews) those who stirred away from Islam, i.e. the Jews (We have forbidden that which We have already) before this surah, and specifically in surah al-An'am (related unto thee) that which We have named to you. (And We wronged them not) because of what We forbade them of meats and fats, (but they were wont to wrong themselves) they were wont to harm, i.e. He forbade them those things because of their sins.
