Mukhtasar Bukhari (Abridged) 1944 — Drinking from a water skin

Abu Huraira (may Allah be pleased with him) reports that the Messenger of Allah (peace and blessings of Allah be upon him) forbade drinking from the mouth (opening) of a water-skin or water-bag (the narrator is unsure), and also forbade that anyone should prevent his neighbor from driving a peg into his wall.
