Surah Al-An'am (The Cattle), Verse 146

وَعَلَی الَّذِیْنَ هَادُوْا حَرَّمْنَا كُلَّ ذِیْ ظُفُرٍ وَمِنَ الْبَقَرِ وَالْغَنَمِ حَرَّمْنَا عَلَیْهِمْ شُحُوْمَهُمَاۤ اِلَّا مَا حَمَلَتْ ظُهُوْرُهُمَاۤ اَوِ الْحَوَایَاۤ اَوْ مَا اخْتَلَطَ بِعَظْمٍ ذٰلِكَ جَزَیْنٰهُمْ بِبَغْیِهِمْ وَاِنَّا لَصٰدِقُوْنَ ۟

Wa 'alal lazeena haadoo harramnaa kulla zee zufurinw wa minal baqari walghanami harramnaa 'alaihim shuhoo mahumaaa illaa maa hamalat zuhooruhumaaa awil hawaayaaa aw makhtalata bi'azm; zaalika jazainaahum bibaghyihim wa innaa la saadiqoon

“For those who followed the Jewish Law, We forbade every (animal) with undivided hoof, and We forbade them the fat of the ox and the sheep, except what adheres to their backs or their entrails, or is mixed up with a bone: this in recompense for their wilful disobedience: for We are true (in Our ordinances).”
