Sahih Bukhari Volume 9, Book 83, Hadith Number 52.

Narrated By Abu Said Al-Khudri : A Jew whose face had been slapped (by someone), came to the Prophet and said, “O Muhammad! A man from your Ansari companions slapped me. ” The Prophet said, “Call him”. They called him and the Prophet asked him, “Why did you slap his face?” He said, “O Allah’s Apostle! While I was passing by the Jews, I heard him saying, ‘By Him Who chose Moses above all the human beings.’ I said (protestingly), ‘Even above Muhammad?’ So I became furious and slapped him.” The Prophet said, “Do not give me preference to other prophets, for the people will become unconscious on the Day of Resurrection and I will be the first to gain conscious, and behold, I will Find Moses holding one of the pillars of the Throne (of Allah). Then I will not know whether he has become conscious before me or he has been exempted because of his unconsciousness at the mountain (during his worldly life) which he received.”
