Ubaidullah bin Abdullah narrates from his father (Sayyiduna Abdullah bin Umar). The Prophet Muhammad (peace be upon him) was asked about such water from which wild beasts and animals also come and drink. The Prophet Muhammad (peace be upon him) said: "When the water reaches two qullahs, nothing makes it impure." (Imam Ibn Hibban, may Allah have mercy on him, says:) These words are for conveying information. It means to inform about the thing that was asked about. Its meaning is that none of the things about which the question was asked make it impure.
