Al-'Imran (The Family of Imran)
Surah 3 · Verse 93
All food was lawful to the children of Israel except that which Israel (Yaqub) had made unlawful for himself before the Torah was sent down. Say, “Bring the Torah and read it, if you are truthful.”
“Muslims used as food the flesh and milk of camel. The Jews criticized them saying that it was unlawful. They are informed that Israel (i.e. Yaqoob PBH) had made it unlawful only on himself long before the Torah was revealed to Musa (PBH), and even in the Torah with them i.e. during the period of Prophet Muhammed (PBH) it was not written as prohibited, therefore they are asked to refer to it. Even after this if they fabricate a lie against Allah (SWT) that camel is forbidden as food, then they are the unjust.”
