Sayyiduna Umar bin Khattab (may Allah be pleased with him) narrates: Once I felt playful, so I kissed (my wife) while I was fasting. I presented myself before the Prophet (peace and blessings of Allah be upon him) and said: Today I have committed a great sin. The Prophet (peace and blessings of Allah be upon him) asked: What is that? I replied: I kissed (my wife) while I was fasting. The Prophet (peace and blessings of Allah be upon him) said: What do you think, if you rinse your mouth with water (what will happen to your fast)? I replied: In that case, there will be no harm. The Prophet (peace and blessings of Allah be upon him) said: Then how is this (any different)?
