The Book of Prayers (Kitab Al-Salat)

Muslim :: Book 4 : Hadith 1145

Jabir reported: The Messenger of Allah (may peace be upon him) forbade eating of onions and leek. When we were overpowered by a desire (to eat) we ate them. Upon this he (the Holy Prophet) said: He who eats of this offensive plant must not approach our mosque, for the angels are harmed by the same things as men.
