Albert Barnes Commentary Leviticus 11:4

"Nevertheless these shall ye not eat of them that chew the cud, or of them that part the hoof: the camel, because he cheweth the cud but parteth not the hoof, he is unclean unto you." — Leviticus 11:4 (ASV)

Divideth not the hoof - The toes of the camel are divided above, but they are united below in a sort of cushion or pad resting upon the hard bottom of the foot, which is “like the sole of a shoe.” The Muslims eat the flesh of the camel, but it is said not to be wholesome.
