Musannaf Ibn Abi Shayba 27:132

Affan narrated to us, he said: Sulaym ibn Hayyan narrated to us, he said: Sa'id ibn Mina narrated to us, from Jabir ibn Abdullah, from the Prophet (peace and blessings of Allah be upon him), who said: "My likeness and the likeness of the prophets is like a man who built a house, then he completed it and perfected it, except for the place of a brick. So people began to enter it and marvel at it, and they would say: 'If only this place for the brick were filled.'" The Messenger of Allah (peace and blessings of Allah be upon him) said: "So I am that place of the brick; I have come and sealed the prophets."
