Musnad Ahmad 32:1375

Hashim narrated to us, Shu'bah narrated to us, from Abu al-Tayyah, and Qatadah, and Hamzah al-Dabbi, that they heard Anas ibn Malik saying: From the Prophet, peace and blessings of Allah be upon him: "I and the Hour have been sent like this," and he gestured with his index and middle fingers. And Qatadah used to say: "Like the precedence of one of them over the other."
