Prophet (peace and blessings of Allah be upon him) a man came and said,
“O Messenger of Allah, I have been destroyed.” He asked him, “What has
happened to you?” He replied, “I had intercourse with my wife while I was
fasting.” The Messenger of Allah (peace and blessings of Allah be upon him)
then told him, “Do you have a slave that you can free?” He replied, “No.” He
then said, “Can you fast two months consecutively?” he replied, “No.” The
Messenger of Allah (peace and blessings of Allah be upon him) then asked
him, “Can you feed sixty poor people?” He replied, “No.” The Prophet (peace
and blessings of Allah be upon him) then kept silent when a big basket full
of dates was brought to him. He said, “Where is the questioner?” The man
replied, “It is I.” The Messenger of Allah (peace and blessings of Allah be
upon him) told him, “Take these dates and give them in charity.” The man
said, “To someone poorer than I, O Messenger of Allah (peace and blessings
of Allah be upon him)? By Allah, there is no family between Madinah’s
mountains poorer than I.” The Prophet (peace and blessings of Allah be upon
him) laughed to such an extent that his premolars could be seen. He then
said, “Feed your family with it.”

Things that do not break the fast
If a person accidently eats, drinks or swallows anything it does not break his fast and they should continue fasting.
Abu Hurayrah (may Allaah be pleased with him) said: The Prophet (peace and blessings of Allaah be upon him) said: “Whoever forgets he is fasting and eats or drinks, let him complete his fast for it is Allaah Who has fed him and given him to drink.” ( Bukhari and Muslim)

Having a shower, bath or immersing one's self in water does not break the fast as long as one does not swallow the water.
Involuntary vomiting does not break the fast.
The scholars of the Standing Committee said:
If there are ulcers on his gums or they bleed when he uses the miswaak, it is not permissible to swallow the blood and he has to spit it out. But if it enters his stomach without him meaning it to or swallowing it deliberately, there is no sin on him. The same applies to vomit, if it goes back into his stomach without him meaning it to, then his fast is still valid. End quote.
