It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that once someone asked the Prophet (peace and blessings be upon him) about this issue: If a person finds such water in the wilderness where animals and beasts also come, can ablution be performed with it? I heard that the Prophet (peace and blessings be upon him) said: "When the water is equal to two pitchers, it does not carry impurity (impurity does not permeate it)."
