﴿ ۞ كُلُّ ٱلطَّعَامِ كَانَ حِلًّۭا لِّبَنِىٓ إِسْرَٰٓءِيلَ إِلَّا مَا حَرَّمَ إِسْرَٰٓءِيلُ عَلَىٰ نَفْسِهِۦ مِن قَبْلِ أَن تُنَزَّلَ ٱلتَّوْرَىٰةُ ۗ قُلْ فَأْتُوا۟ بِٱلتَّوْرَىٰةِ فَٱتْلُوهَآ إِن كُنتُمْ صَٰدِقِينَ ﴾

“ALL FOOD was lawful unto the children of Israel, save what Israel had made unlawful unto itself [by its sinning] before the Torah was bestowed from on high. Say: "Come forward, then, with the Torah and recite it, if what you say is true!"”
