It is narrated from Hazrat Abu Darda (may Allah be pleased with him) that once the Prophet vomited, so the Prophet (peace and blessings be upon him) broke his fast. The narrator says that then I met the freed slave of the Prophet, Hazrat Thawban, in the mosque of Damascus and said to him that Hazrat Abu Darda (may Allah be pleased with him) has told me that when the Prophet vomited, the Prophet (peace and blessings be upon him) broke his fast. He said that Hazrat Abu Darda (may Allah be pleased with him) has spoken the truth; it was I who poured water for the Prophet.
