It is narrated from Sayyiduna Ali (may Allah be pleased with him) that he said: The Messenger of Allah (peace and blessings be upon him) called me and said: "O Ali! In you there is a likeness of Isa (peace be upon him): the Jews hated him so much that they slandered his mother, and the Christians loved him (so excessively) that they raised him to a rank that was not his." Sayyiduna Ali (may Allah be pleased with him) said: "Beware! Two kinds of people will also perish concerning me: a lover who exaggerates and praises me for what is not in me, and a slanderous hater whose hatred of me drives him to fabricate lies against me. Remember! I am neither a prophet, nor is revelation sent down to me; rather, I act upon the Book of Allah and the Sunnah of the Prophet (peace and blessings be upon him) as far as I am able. So whatever I command you of obedience to Allah, obeying me in it is binding upon you, whether you like it or dislike it. But if I or anyone else commands you to disobey Allah, then remember that there is no obedience to anyone in disobedience to Allah, the Mighty and Majestic; obedience is only in what is good (ma'ruf)." The chain of this hadith is sahih (authentic), but the two Shaykhs did not record it.
