Abu Dawud Book 20, Hadith Number 3707.
Chapter : On nabidh datedrink when it ferments.
Narated By Abu Hurayrah : I knew that the Apostle of Allah (PBUH) used to keep fast. I waited for the day when he did not fast to present him the drink (nabidh) which I made in a pumpkin. I then brought it to him while it fermented. He said: Throw it to this wall, for this is a drink of the one who does not believe in Allah and the Last Day.
