Musannaf Ibn Abi Shaybah

Hazrat Jabir bin Abdullah (may Allah be pleased with him) narrates that the Prophet ﷺ said: My example and the example of the prophets before me is like that of a man who built a house and completed it except for the place of one brick. So people would enter it and marvel at it and say, "If only this place for the brick were filled, it would be good." The Messenger of Allah ﷺ said: I am that place of the brick; I have come and I have completed the line of prophets.
