Sayyidah Fatimah (may Allah be pleased with her), the daughter of the Prophet (peace and blessings be upon him), narrates: On the evening of Arafah the Prophet (peace and blessings be upon him) came out to us and said: "Indeed Allah Almighty has expressed pride in you, and He has forgiven you all in general and Ali in particular. I am the Messenger of Allah to you, and I do not show favouritism to my relatives. This is Jibril telling me that truly fortunate is the one who loves Ali during his life and after his death, and utterly wretched is the one who hates Ali during his life and after his death."
Al-Tabarani recorded this narration. Its chain contains narrators whom I do not know.
