It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that a woman came to the Messenger of Allah (peace and blessings be upon him) carrying her child and said, "O Messenger of Allah! He has some affliction; whenever it occurs during eating, he spoils all our food." The Prophet (peace and blessings be upon him) passed his hand over the child's chest and prayed for him. Suddenly, the child vomited, and something like a black cat came out of his mouth and ran away.
