Musannaf Ibn Abi Shaybah

Hazrat Ibn Abbas (may Allah be pleased with them both) narrates that a woman brought her son to the Prophet ﷺ and said, "O Messenger of Allah! My son is afflicted with madness, and it overcomes him at noon and in the evening, and he performs bad actions." It is said that the Messenger of Allah ﷺ passed his hand over his chest and prayed. The boy vomited, and from his stomach came out a living creature in the shape of a large black rat.
