۞ كُلُّ ٱلطَّعَامِ كَانَ حِلّٗا لِّبَنِيٓ إِسۡرَٰٓءِيلَ إِلَّا مَا حَرَّمَ إِسۡرَٰٓءِيلُ عَلَىٰ نَفۡسِهِۦ مِن قَبۡلِ أَن تُنَزَّلَ ٱلتَّوۡرَىٰةُۚ قُلۡ فَأۡتُواْ بِٱلتَّوۡرَىٰةِ فَٱتۡلُوهَآ إِن كُنتُمۡ صَٰدِقِينَ ٩٣
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."
Translation: Saheeh International (English)
Each word's meaning and sound
All wholesome foods were lawful for the Israelites, except which Jacob (peace be upon him) had made unlawful for himself before the Torah was revealed. These were not, as the Jews claimed to the Prophet Muhammad, made unlawful in the Torah. Tell them, O Prophet, to bring the Torah and read it if they are telling the truth in what they claim. When the Jews heard this, they did not know how to respond, so they did not bring the Torah to recite to him. This is an example of the Jews changing things and not telling the truth about what was in the Torah.
