I heard Ibn ‘Umar saying: The Messenger of Allah (ﷺ) forbade (the preparation of Nabidh) in a green pitcher (besmeared with pitch), in varnished jar, and in gourd, and he said: Prepare Nabidh in small waterskins.
I went to Hudhaifa b. Yaman and said to him: Narrate what you have heard from Allah’s Messenger (ﷺ) pertaining to the Dajjal. He said that the Dajjal would appear and there would be along with him water and fire and what the people would see as water that would be fire and that would burn and what would appear as fire that would be water and any one of you who would see that should plunge in that which he sees as fire for it would be sweet, pure water, and ‘Uqba said: I also heard it, testifying Hudhaifa.
