Silsilah as-Sahihah 1925 — Ruling on drinking directly from a water

It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) forbade drinking water directly from the mouth of a water-skin. Ayyub says: I have come to know that a man drank water from the mouth of a water-skin, and a snake came out from inside it.
