"People are the only animals that drink the milk of the mother of another species. All other animals stop drinking milk altogether after weaning. It is unnatural for a dog to nurse from a mother giraffe; it is just as unnatural for a human being to drink the milk of a cow."

Blessed the man that hath visited `Akká, and blessed he that hath visited the visitor of `Akká. Blessed the one that hath drunk from the Spring of the Cow and washed in its waters, for the black-eyed damsels quaff the camphor in Paradise, which hath come from the Spring of the Cow, and from the Spring of Salvan (Siloam), and the Well of Zamzam. Well is it with him that hath drunk from these springs, and washed in their waters, for God hath forbidden the fire of hell to touch him and his body on the Day of Resurrection.
