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

‘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.

Narrated from Umm Ayyub Ansari (may Allah be pleased with her) that the Prophet Muhammad (peace and blessings be upon him) (after migration) stayed at their house. They prepared a sumptuous meal for him in which there were some of those vegetables (such as garlic, etc.). The Prophet disliked eating it and said to the companions: "You eat it, for I am not like you. I fear that I may cause discomfort to my companion (Jibril)." Imam Tirmidhi says:
1- This hadith is Hasan Sahih Gharib,
2- Umm Ayyub is the wife of Abu Ayyub Ansari.

Abu Al-Aliyah says that garlic is lawful sustenance. Abu Khulda's name is Khalid bin Dinar; he is considered trustworthy by the hadith scholars. He met Anas bin Malik and heard hadith from him. Abu Al-Aliyah's name is Rafi', and he is Rafi' al-Riyahi. Abdur Rahman bin Mahdi says: Abu Khulda was a righteous Muslim.
