Musnad Ahmad 30:468

Abu Kamil narrated to us, Ibrahim narrated to us, Ibn Shihab narrated to us, from Abu Salamah ibn Abd al-Rahman and Abd al-Rahman al-A’raj, from Abu Hurairah, who said: Two men insulted each other, a man from the Muslims and a man from the Jews. The Muslim said, "By the One who chose Muhammad over the worlds." The Jew said, "By the One who chose Moses over the worlds." The Muslim became angry and slapped the Jew’s eye. The Jew came to the Messenger of Allah, peace and blessings of Allah be upon him, and informed him of that. The Messenger of Allah, peace and blessings of Allah be upon him, called him and asked him, and he confessed to that. The Messenger of Allah, peace and blessings of Allah be upon him, said: "Do not prefer me over Moses, for the people will be struck unconscious on the Day of Resurrection, and I will be the first to recover. I will find Moses holding onto the side of the Throne. I do not know: was he among those who were struck unconscious and recovered before me, or was he among those whom Allah, the Mighty and Majestic, exempted?"
