For those who are allowed not to fast:

People suffering from the following problems are allowed not to fast during the month of Ramadan. But once the problem is over, it should be done. And if he never gets over the problem and dies while suffering from that problem, it is enough to pay fidya on the condition that he is able. 1. Suffering from a deadly disease. 2. Staying on Shari'i tour. 3. Forced by terrorists not to fast. 4. Being pregnant or lactating. If you fast in such a situation, there is a fear of death of yourself or your child. 5. To die of hunger or thirst. 6. to grow old

If a person is suffering from a serious disease and cannot fast because of this, or if an experienced Muslim doctor says that fasting will cause you to suffer from a serious disease, then it is permissible for such people not to fast.

If a person is very old and is unable to fast because of this, he can pay fidya without fasting. If he is unable to fast and is unable to pay fidya then the person should seek forgiveness from Allah. Besides, he has nothing else to do.

It is not permissible for a person to break the fast of that day until he leaves the house during the day of the intention of travel, if he breaks the fast and then departs, then the qaza of that fast will become obligatory on him.

It is makruh to gargle while performing ablution while fasting, and to draw water into the nose.
