But if the stay he intends exceeds four days, he is considered a resident. The concessions granted to a traveller no longer apply to him, and he must fast and perform the prayers in full, because by resolving to remain for more than four days he has effectively left the state of travel.

Breaking the Fast for Pregnant and Nursing Women
Question: When is it permissible for a pregnant or a nursing woman to break the fast in Ramadan?
Answer: A pregnant or nursing woman may break the fast if she fears that fasting will harm her child, for the nourishment reaching the child in the womb—or, in the case of a nursing mother, through her milk—could be diminished. If that is the situation, she may break the fast, make up the missed days later, and, in addition, feed one needy person for every day missed.

If, however, she fears for herself—because she is unable to fast while pregnant or while nursing due to her own weakness—then she may break the fast and make up the missed days later, but no feeding is required of her. Thus, if she fears for herself, only making up the fasts is necessary; but if she fears solely for her child and not for herself, both making up the days and feeding are required. This is the ruling concerning when a pregnant or nursing woman may break the fast.

Question: Does the same ruling apply to someone who breaks the fast, for example, to rescue another person from danger—that is, must he both make up the fast and feed the poor?
Answer: Yes. A person may break his fast in order to save another from destruction if
