Sayyiduna Ibn Umar (may Allah be pleased with them both) narrated that the Noble Prophet (peace and blessings be upon him) said at the time of the Battle of Khaybar that whoever has eaten from this tree, meaning garlic, should not come to our mosque.

Abdul Aziz (may Allah have mercy on him) narrated that a person asked Sayyiduna Anas bin Malik (may Allah be pleased with him), "What have you heard from the Prophet (peace and blessings of Allah be upon him) about garlic?" He replied that the Prophet (peace and blessings of Allah be upon him) said, "Whoever eats from this tree should not come near us," or he said, "should not pray with us."

Sayyiduna Jabir bin Abdullah (may Allah be pleased with him) narrates that the Noble Prophet (peace and blessings be upon him) said: Whoever has eaten garlic or onion should keep away from us, or (he said) he should stay away from our mosque, or he should remain sitting in his house. A pot was brought to the Noble Prophet (peace and blessings be upon him) in which there were various kinds of green vegetables (including onion or leek). The Prophet (peace and blessings be upon him) sensed the smell in it and inquired about it. He was informed of all the vegetables that had been added to the dish. There was a companion present there. The Prophet (peace and blessings be upon him) said: Pass this dish towards him. The Prophet (peace and blessings be upon him) did not like to eat it and said: You people eat it, for I have intimate conversation with those (angels) with whom you do not.
