Sayyiduna Umar bin Al-Khattab (may Allah be pleased with him) said: I came in a state of happiness and kissed (my wife) while I was fasting. Then I went to the Messenger of Allah (peace and blessings be upon him) and said: Today I have committed a great sin; I was fasting and I kissed (my wife). The Messenger of Allah (peace and blessings be upon him) said: "What do you think if you rinse your mouth with water while fasting?" I said: There is no harm in that. He said: "Then why should there be any harm in this?"
