Musannaf Ibn Abi Shayba 23:221

Aswad ibn Amir narrated to us, he said: Bukayr ibn Abi al-Sumayt narrated to us, he said: I heard Muhammad ibn Sirin being asked about a man who saw in a dream as if he had a drawn sword with him. He said: "A male child." He said: "The sword broke." He said: "He will die." He said: And Ibn Sirin was asked about stones in a dream, and he said: "Hard-heartedness." And he was asked about wood in a dream, and he said: "Hypocrisy."
