CR # (1691) The carcass and its parts are unclean if the animal is not of the cold blooded animals, except furs, wool, feathers, horns, claws, eggs, (provided, the outer shell has hardened even if it is from the inedible animals) and rennet.

CR # (1692) From the animal slaughtered, according to the popular view the following parts are not edible:

(1) The penis.

(2) The testicles. (3) The spleen. (4) The dung dropping. (5) Blood. (6) Gall bladder. (7) The bladder. (8) The placenta. (9) The vagina. (10) Two large vertebral muscles extended from the neck to the tail. (11) The spinal marrow.

(12) The glands.

(13) The small gland under the brain. (14) And the eyes. (15) A small piece between the hoof. The non-edibility of some of these items is objectionable, however, the precautionary rule should be observed. In birds, according to a more clear reason there is nothing like those mentioned above except the waste blood, gallbladder, the spleen and testicles in some of them. The kidney, and the ears of heart (a piece that looks like ears and is attached to it) are detestable to eat.

CR # (1693) The unclean substances are not lawful for food like human feces and a piece separated from living animal, also soil except very little not bigger than a lentil's grain of the soil from the grave-site of Imam Hussain used for blessings. The minerals, stones, and trees are not lawful.
