‘Ali (may Allah be pleased with him) says that garlic has been prohibited except when it is cooked 1.

Jabir (may Allah be pleased with him) reports that the Messenger of Allah (peace and blessings of Allah be upon him) said: "Whoever among you eats garlic, or eats garlic, onion, or leek, should not come near us in our mosques." __QUR_N__

Imam Tirmidhi says:
1- This hadith is hasan sahih.
2- In this chapter, hadiths have also been narrated from Umar, Abu Ayyub, Abu Hurairah, Abu Sa'id al-Khudri, Jabir bin Samurah, Qurrah bin Iyas al-Muzani, and Ibn Umar (may Allah be pleased with them all).

Jabir bin Samurah (may Allah be pleased with him) says that the Messenger of Allah (peace and blessings of Allah be upon him) (after migration) stayed at the house of Abu Ayyub Ansari (may Allah be pleased with him). Whenever he ate food, he would send a portion of it to Abu Ayyub Ansari (may Allah be pleased with him). One day, he sent back the (entire) food (untouched); the Prophet (peace and blessings of Allah be upon him) had not eaten any of it. When Abu Ayyub came to the Prophet (peace and blessings of Allah be upon him) and mentioned this to him, he said: "Does it have garlic in it?" He asked: "O Messenger of Allah! Is it forbidden?" He replied: "No, but because of its smell, I dislike it." Imam Tirmidhi says:
This hadith is Hasan Sahih.

‘It is narrated from Shareek bin Hanbal that Ali (may Allah be pleased with him) considered eating garlic to be disliked, except if it was cooked.’ Imam Tirmidhi says:
1- The chain of this hadith is not very strong; this is the statement of Ali (may Allah be pleased with him),
2- Through the chain of Shareek bin Hanbal, this hadith has also come from the Prophet (peace and blessings of Allah be upon him) in a mursal manner,
3- Muhammad bin Ismail Bukhari says: The narrator Jarrah bin Maleeh is truthful, and Jarrah bin Duhak is maqaarib al-hadith.
