Abu Dawud Book 21, Hadith Number 3815.

Chapter : Not known.

Narated By Hudhayfah ibn al-Yaman : Zirr ibn Hubaysh said: Hudhayfah traced, I think, to the Apostle of Allah (PBUH) the saying: He who spits in the direction of the qiblah will come on the Day of Resurrection in the state that his saliva will be between his eyes; and he who eats from this noxious vegetable should not come near our mosque, saying it three times.
