According to a Hadith transmitted by Imam Ahmad, Rasulallah (s.a.w) said to Hazrat Ali, "You have a resemblance to Jesus, whom the Jews hated so much that they slandered his mother and whom Christians loved so much that they placed him in a position not rightly his."
Hazrat Ali afterwards said, "Two types of people will perish on my account, one who loves me so excessively that he praises me for what I do not possess, and one who hates me so much that he will be impelled by his hatred to slander me."
