Sahih Muslim 194b

It is reported on the authority of Abu Huraira that there was placed before the Messenger of Allah a cup of soft bread, soup and meat. He took part of the foreleg which he liked most. He sliced (with his teeth) a slice (out of that) and said:

I would be the leader of mankind on the Day of Resurrection. He then sliced (that meat) for the second time and said: I am the leader of mankind on the Day of Resurrection. When he saw that his companions did not ask him (about this assertion) he said: Why don't you say: How would that be? They said: How would be it, Messenger of Allah? He said: People would stand before the Lord of the worlds. And the rest of the hadith was narrated like the one transmitted by Abu Hayyan, on the authority of Abu Zur'a, and in the story of Ibrahim, this addition was made. He said and made mention of his words with regard to the star: This is my Lord. And his words with regard to their gods: But the big among them has done that. And his words: I am ailing. He (the Holy Prophet) said: By Him in Whose Hand is the life of Muhammad, the distance between two leaves of the door from their supporting frames is as the distance between Mecca and Hajar or Hajar and Mecca. I do not remember how he said it (whether Mecca and Hajar or Hajar and Mecca).
