Qur'an 6:146

وَعَلَى ٱلَّذِينَ هَادُوا۟ حَرَّمْنَا كُلَّ ذِى ظُفُرٍ ۖ وَمِنَ ٱلْبَقَرِ وَٱلْغَنَمِ حَرَّمْنَا عَلَيْهِمْ شُحُومَهُمَآ إِلَّا مَا حَمَلَتْ ظُهُورُهُمَآ أَوِ ٱلْحَوَايَآ أَوْ مَا ٱخْتَلَطَ بِعَظْمٍ ۚ ذَٰلِكَ جَزَيْنَـٰهُم بِبَغْيِهِمْ ۖ وَإِنَّا لَصَـٰدِقُونَ

Unto those who are Jews We forbade every animal with claws. And of the oxen and the sheep forbade We unto them the fat thereof save that upon the backs or the entrails, or that which is mixed with the bone. That we awarded them for their rebellion. And lo! we verily are truthful.
