Sunan Ibn Majah, Chapter: The Chapters of Purification and its Sunnah

that on the night of the jinn, the Messenger of Allah (saw) said to him: "Do you have water for ablution?" He said: "No, I have nothing but some Nabidh* in a vessel." He said: "Good dates and pure water. (i.e., there is no harm from the mixing of the two)." So he performed ablution with it. This is the narration of Waki. (Daif) *Water in which grapes or dates are soaked, but not fermented.
