Musannaf Ibn Abi Shayba 27:504

Muhammad ibn Bishr narrated to us, he said: Abu Makin informed us, from Khalid Abu Umayyah: That Ali passed by a house in the paths of his house, and a piece of a brick or a fragment of a brick fell upon him. So he supplicated to Allah that its construction not be completed. He said: So not a single brick was placed upon another in it.
