What is the ruling on sweeping and cleaning that leads to the rising of dust and particles while fasting during the daytime in Ramadan?

If dust reaches the mouth unintentionally, it does not invalidate the fast. Sweeping and cleaning are permissible for the fasting person, and whatever reaches their stomach from that unintentionally does not invalidate their fast. A fasting person is not required to keep their mouth closed during dusty conditions or sifting, due to hardship.
