´It was narrated from 'Abdullah bin Mas'ud that :` On the night of the jinn, the Messenger of Allah 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'.
