Abu Huraira reported Allah's Messenger (ﷺ) as saying:

The similitude of mine and that of the Apostles (before me) is that of a person who constructed a building and he built it fine and well and the people went round it saying: Never have we seen a building more imposing than this. but for one brick, and I am that brick (with which you give the finishing touch to the building). And I am the last of the Apostles. (Muslim)
