Ali 'Imran 93

۞ كُلُّ ٱلطَّعَامِ كَانَ حِلًّا لِّبَنِىٓ إِسْرَٰٓءِيلَ إِلَّا مَا حَرَّمَ إِسْرَٰٓءِيلُ عَلَىٰ نَفْسِهِۦ مِن قَبْلِ أَن تُنَزَّلَ ٱلتَّوْرَىٰةُ ۗ قُلْ فَأْتُوا۟ بِٱلتَّوْرَىٰةِ فَٱتْلُوهَآ إِن كُنتُمْ صَـٰدِقِينَ

kullu l-ṭaʿāmi kāna ḥillan libanī is'rāīla illā mā ḥarrama is'rāīlu ʿalā nafsihi min qabli an tunazzala l-tawrātu qul fatū bil-tawrāti fa-it'lūhā in kuntum ṣādiqīna

All food was lawful to the Children of Israel except what Israel [i.e., Jacob] had made unlawful to himself before the Torah was revealed. Say, [O Muḥammad], "So bring the Torah and recite it, if you should be truthful."
