Abu Shabiyah Mehri, may Allah have mercy on him, who used to preach in Constantinople, says: Once a person requested Hazrat Thawban, may Allah be pleased with him, to narrate a hadith from the Prophet Muhammad, peace and blessings be upon him. He replied: I have seen that once the Prophet Muhammad, peace and blessings be upon him, vomited, so the Prophet Muhammad, peace and blessings be upon him, broke his fast.
