The complete and detailed Qur’an tells us:
6:146 For those who are Jewish, We had prohibited some edibles, such as animals with undivided hoof, the fat of the cow and the sheep, except what is attached to their backs or their intestines, or what is mixed-up in the bone. But that was ONLY A TEMPORARY RETRIBUTION FOR THEIR DISOBEDIENCE (4:160). We are absolutely True to Our Word.
The camels were categorized as having nails coming out of the toes divided, but having and walking on undivided pads like cats and dogs. Thus deeming camels as having undivided hooves, and hence prohibited.
