1722. A traveler who has to offer two rak‘ah for every four rak‘ah prayer, should not fast. As for a traveler who offers his prayer in full, such as someone whose profession is travelling, or has embarked on a sinful journey, he must fast while travelling.
1723. There is not problem in travelling during the month of Ramadan, albeit it is makrÙh, even if it is not for the purpose of avoiding the fasts, unless his journey is borne out of necessity, or—according to some narrations—is for going to Hajj or ‘umrah.
1724. If a person is obligated to fast on a particular day, other than the fast of the month of Ramadan, and if that obligation is borne out of a person’s right over him, such as someone who has been hired to fast on a particular day, then he cannot travel on that day. The same will apply, based on obligatory precaution, to a date-specific obligatory fast other than the fast of a nadhr, such as the fast for the third day of i‘tikÁf. However, if the fast has become obligatory on a particular day due to a nadhr, then the stronger opinion is that the person can travel on that day, and fast on a day other than that day.
1725. If a person makes a nadhr to fast without specifying its exact day, he cannot observe it while travelling. However, if he makes a nadhr to fast on a particular date while travelling, he will have to observe it while travelling. Similarly, if he makes a nadhr to fast on a particular day, be he traveling or not, then he must fast on that day even if he is traveling.
1726. A traveler can fast recommended fasts for three days in Madina, for seeking the fulfillment of his needs. The obligatory precaution in this case is that the three days should be Wednesday, Thursday and Friday.
1727. If a person does not know that the fast of a traveler is not valid, and fasts while travelling, but realizes during the day, his fast will be invalidated. However, if he does not find out until maghrib, his fast will be in order.
فراموش کردن سفر و اینکه روزه مسافر باطل است
مسأله 1728 ـ اگر فراموش كند كه مسافر است ، يا فراموش كند كه روزه مسافر باطل مى باشد و در سفر روزه بگيرد ، روزه او باطل است.
1729. If a person who is fasting embarks on a journey after zuhr, he must complete his fast. If he travels before zuhr, his fast will be invalidated the moment he reaches the limit of permissibility. Should he commit an act which invalidates the fast prior to reaching it, the kaffÁrah will become obligatory on him.
1730. If a traveler reaches his hometown prior to zuhr in the month of Ramadan, regardless of whether he was journeying before fajr or he embarked on his journey whilst fasting, and has not committed any act which invalidates the fast, then he must observe the fast of that day. If he has committed such an act, the fast of that day will be void. The same will apply to a person who reaches a place where he intends to stay for ten days.
1731. If a traveler reaches his hometown after zuhr, or a place where he intends to reside for ten days, his fast for that day will not be valid.
1732. It is makrÙh for a traveler or one who is excused from fasting to engage in intercourse during days of the month of Ramadan, eat more than his fill or completely quench his thirst.
