Musnad Ahmed: Hadith 4323

On the night of the jinn, the Messenger of Allah (ﷺ) drew a line around him, and one of them would come looking like the shape of a palm tree. He said to me: “Do not move from your place." And he recited the Book of Allah, may He be glorified and exalted, to them. When he (Ibn Mas'ood) saw az-Zutt (a kind of black people who are known to be tall and slim) he said: They are just like these ones. And the Prophet (ﷺ) said: “Do you have any water?” I said: No. He said: "Do you have any nabeedh?" I said: Yes. And he did wudoo’ with it.
