It is narrated from Hazrat Fadala (may Allah be pleased with him) that one day the Noble Prophet (peace and blessings be upon him) came to us. On that day, he would generally be fasting. The Noble Prophet (peace and blessings be upon him) asked for a vessel of water and drank from it. We said, "O Messenger of Allah! On this day you used to fast." The Noble Prophet (peace and blessings be upon him) said, "Yes! But today I vomited."
