Musannaf Ibn Abi Shaybah 25796 — Covering drink and tying

It is narrated from Sayyiduna Jabir (may Allah be pleased with him) that Sayyiduna Abu Humayd (may Allah be pleased with him) came to the Prophet (peace and blessings be upon him) with a drink while he (peace and blessings be upon him) was at al-Baqi'. He (peace and blessings be upon him) said: "Why did you not cover it, even if only by placing a piece of wood across it?"
