info@masjidmuhammad.ukQuestion:
Does using toothpaste while fasting invalidates the fast?
Answer:
It is makruh to use toothpaste while fasting unless there is a severe
need to use it. As long as it does not go down the throat, the fast will
not break. There is leeway to use it at the time of a genuine need.
Āp Ke Masa’il:
It is makruh to use toothpaste while fasting. Nonetheless, if it does not
go down the throat, the fast does not break.
Kitab al-Fatawa:
Toothpaste has a taste to it, and it is makruh to taste anything that has
taste while fasting. One should therefore avoid using toothpaste while
fasting.
Since its taste – like a fresh miswak – is neither desired by the stomach
nor the brain, and is a means to cleaning the teeth, too much of
emphasis should not be placed on its disapproval. In my view, its taste
is similar to that of a miswak. I think labelling its use as makruh needs
to be investigated.
Observe the following from Fatawa al-Lajnah ad-Da’imah Li al-Buh’th al-
‛Ilmiyyah Wa al-Ifta’:
Allah ta‛ala knows best.
