Musannaf Ibn Abi Shaybah

Hazrat Abu Saeed Khudri narrates that someone asked, "O Messenger of Allah (peace and blessings be upon him)! Can we perform ablution with the water of Buda'ah well, even though it is a well into which menstrual cloths, the flesh of dogs, and filth are thrown?" The Noble Prophet (peace and blessings be upon him) replied: "Water is pure; nothing makes it impure."

It is narrated from Hazrat Ibn Abbas (may Allah be pleased with them both) that one of the pure wives of the Noble Prophet (peace and blessings be upon him) performed ghusl (ritual bath) in a tub. Then the Noble Prophet (peace and blessings be upon him) came, and he wished to perform ghusl or wudu with that water. The pure wife said: O Messenger of Allah (peace and blessings be upon him)! I was in a state of janabah (ritual impurity). The Prophet (peace and blessings be upon him) said: Water does not become impure by janabah.

It is narrated from Hazrat Abdullah bin Umar (may Allah be pleased with both of them) that the Messenger of Allah (peace and blessings be upon him) said: When water reaches the amount of two qullahs, it does not bear impurity. And (Imam) Abu Hanifa's opinion has been mentioned that: the water becomes impure.
