Sahih Muslim Book 41, Hadith Number 7045.

Anas b. Malik reported that Allah’s Messenger (way peace be upon him) said: I and the Last Hour have been sent like this. Shu’ba said: I heard Qatada as saying in his narration: The excellence of one over the other. And I do not know whether he narrated it from Anas or Qatada himself said so.
