Al-Lu'lu Wal-Marjan 333 — The Book of Mosques and Places of Worship.

Jabir bin `Abdullah Narrated from:

The Prophet صلى الله عليه وسلم said, "Whoever eats garlic or onion should keep away from us", or said: "Keep away from our mosque or should remain in his house."Jâbir bin 'Abdullâh رضى الله عنه in another narration said, "Once a big pot containing cooked vegetables was brought. On finding unpleasant smell coming from it, the Prophet صلى الله عليه وسلم asked, 'What is in it?' He was told all the names of the vegetables that were in it. The Prophet صلى الله عليه وسلم ordered that it should be brought near to some of his companions who were with him. When the Prophet صلى الله عليه وسلم saw it he disliked to eat it and said, 'Eat ( I don't eat) for I converse with those whom you don't converse with (i.e. the angels).'" ( Sahîh Al-Bukhâri, Hadîth No. 814, Vol. 1)
