Musannaf Ibn Abi Shaybah 1846 — A dog licking from a vessel

It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "If a dog licks from the vessel of any of you, the way to purify it is that you wash it seven times, and clean it with earth the first time."
