The Prophet(pbuh) said, 'My example and the example of the Prophets before me is like a man who built a house, which he built and perfected except for the space on one block; people would go round the house and stare in awe at its perfection and say,'Had it not been for this space!' The Prophet continued, 'I am that brick, I am the last of the Prophets.' (Al-Bukhari)
